Question 1 of 5
1. Question
Solve`3y=4 1/5`Hint
Help VideoCorrect
Excellent!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `y`, it needs to be alone on one side.Remove `3` by dividing both sides of the equation by `3`.`3``y` `=` `4 1/5` `3``y` `=` `21/5` Turn the mixed number into an improper fraction `3``y``:(3)` `=` `(21)/5``:(3)` `y` `=` `(21)/5``times 1/(3)` `3:3` cancels out `y` `=` `(21)/(15)` Simplify `y` `=` `7/5` `y` `=` `1 2/5` Turn the improper fraction back to a mixed number Check our workTo confirm our answer, substitute `y=1 2/5` to the original equation.`3y` `=` `4 1/5` `3(1 2/5)` `=` `4 1/5` Substitute `y=1 2/5` `3(7/5)` `=` `4 1/5` Turn the mixed number into an improper fraction `(21)/5` `=` `4 1/5` `4 1/5` `=` `4 1/5` Turn the improper fraction back to a mixed number Since the equation is true, the answer is correct.`y=1 2/5`

Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `x`, it needs to be alone on one side.Remove `1/(8)` by multiplying both sides of the equation by `8`.`15` `=` $$\frac{\color{#00880A}{x}}{8}$$ `15``times(8)` `=` $$\frac{\color{#00880A}{x}}{8} \color{#CC0000}{\times(8)}$$ `120` `=` `x` `1/(8) times (8)` cancels out `x` `=` `120` Check our workTo confirm our answer, substitute `x=120` to the original equation.`15` `=` `x/(8)` `15` `=` `(120)/(8)` Substitute `x=120` `15` `=` `15` Since the equation is true, the answer is correct.`x=120`

Great Work!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `m`, it needs to be alone on one side.Remove `(1)/9` by multiplying both sides of the equation by `9`.$$\frac{\color{#00880A}{m}}{9}$$ `=` `4` $$\frac{\color{#00880A}{m}}{9} \color{#CC0000}{\times(9)}$$ `=` `4``times(9)` $$\frac{9\color{#00880A}{m}}{9}$$ `=` `36` `m` `=` `36` `9/9` cancels out Check our workTo confirm our answer, substitute `m=36` to the original equation.`(m)/9` `=` `4` `(36)/9` `=` `4` Substitute `m=36` `4` `=` `4` Since the equation is true, the answer is correct.`m=36`

4. Question
Solve`(70)/u=5` `u=` (14)
Hint

Correct!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.First, make sure that the variable is not a denominator by multiplying both sides of the equation by `u`.$$\frac{70}{\color{#00880A}{u}}$$ `=` `5` $$\frac{70}{\color{#00880A}{u}} \times u$$ `=` `5` `times u` `70` `=` `5``u` `1/u times u` cancels out To solve for `u`, it needs to be alone on one side.Remove `5` by dividing both sides of the equation by `5`.`70` `=` `5``u` `70``:5` `=` `5``u``:5` `14` `=` `u` `5:5` cancels out `u` `=` `14` Check our workTo confirm our answer, substitute `u=14` to the original equation.`(70)/u` `=` `5` `(70)/(14)` `=` `5` Substitute `u=14` `5` `=` `5` Since the equation is true, the answer is correct.`u=14`

Well Done!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.First, make sure that the variable is not a denominator by multiplying both sides of the equation by `a`.$$\frac{12}{\color{#00880A}{a}}$$ `=` `6` $$\frac{12}{\color{#00880A}{a}} \times a$$ `=` `6` `times a` `12` `=` `6``a` `1/a times a` cancels out To solve for `a`, it needs to be alone on one side.Remove `5` by dividing both sides of the equation by `5`.`12` `=` `6``a` `12``:(6)` `=` `6``a``:(6)` `2` `=` `a` `(6):(6)` cancels out `a` `=` `2` Check our workTo confirm our answer, substitute `a=2` to the original equation.`(12)/a` `=` `6` `(12)/(2)` `=` `6` Substitute `a=2` `6` `=` `6` Since the equation is true, the answer is correct.`a=2`
