Question 1 of 6
1. Question
Solve`m+9=27` `m=` (18)
Hint
Help VideoCorrect
Well Done!
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.Move `9` to the other side by subtracting `9` from both sides of the equation.`m` `+9` `=` `27` `m` `+9` `9` `=` `27` `9` `m` `=` `18` `99` cancels out Check our workTo confirm our answer, substitute `m=18` to the original equation.`m+9` `=` `27` `18+9` `=` `27` Substitute `m=18` `27` `=` `27` Since the equation is true, the answer is correct.`m=18`

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.Move `11` to the other side by subtracting `11` from both sides of the equation.`x` `+11` `=` `16` `x` `+11` `11` `=` `16` `11` `x` `=` `5` `1111` cancels out Check our workTo confirm our answer, substitute `x=5` to the original equation.`x+11` `=` `16` `5+11` `=` `16` Substitute `x=5` `16` `=` `16` Since the equation is true, the answer is correct.`x=5` 
Question 3 of 6
3. Question
Solve for `x``x+3=6` `x=` (3)
Hint
Help VideoCorrect
Well Done!
Incorrect
Isolate the `x` variable on one side of the equation`x+3` `3` `=` `6` `3` Subtract `3` from both sides `x``+3` `3` `=` `6` `3` `33` cancels out `x` `=` `3` `x=3` 
Question 4 of 6
4. Question
Solve for `x``x+7=9` `x=` (2)
Hint

Excellent!
Incorrect
Isolate the `x` variable on one side of the equation`x+7` `7` `=` `9` `7` Subtract `7` from both sides `x``+7` `7` `=` `9` `7` `77` cancels out `x` `=` `2` `x=2`

Keep Going!
Incorrect
Isolate the `x` variable on one side of the equation`x+3` `3` `=` `7` `3` Subtract `3` from both sides `x``+3` `3` `=` `7` `3` `33` cancels out `x` `=` `4` `x=4` 
Question 6 of 6
6. Question

Hint
Help VideoCorrect
Great Work!
Incorrect
Isolate the `x` variable on one side of the equation`x+2` `2` `=` `11` `2` Subtract `2` from both sides `x``+2` `2` `=` `11` `2` `22` cancels out `x` `=` `9` `x=9`
