Hint
Help VideoCorrect
Well Done!
Incorrect
Rules for Adding and Subtracting Integers
First, plug in the given values`x=-6`
`y=4``x``+``y` `=` `-6``+``4` Now, solve using the number lineStart at `-6`, then since `4` is positive move right `4` places`-6` `+4` `=` 
`-6+4` `=` `-2` `-2` -

Excellent!
Incorrect
Rules for Adding and Subtracting Integers
First, plug in the given values`x=4`
`y=5``y``-2``x` `=` `5``-2(``4``)` `=` `5-8` Solve the multiplication Now, solve using the number lineStart at `5`, then subtract `8` by moving left `8` places`5` `-8` `=` 
`5-8` `=` `-3` `-3` -
Question 3 of 4
3. Question
Substitute `x=4`, `y=5` and `z=-3`, then solve`3xy divide z`- (-20)
Hint

Keep Going!
Incorrect
Rules for Dividing Integers
First, plug in the given values`x=4`
`y=5`
`z=-3``3``x``y``divide``z` `=` `3(``4``)(``5``) divide``-3` Next, solve the multiplication.`3(4)(5)``divide -3` `=` `60``divide -3` Finally, solve the division.`60 divide -3` `=` `-20` Recall, `-20` -
Question 4 of 4
4. Question
Substitute `x=6` and `y=-5`, then solve`-3+3x+3y`- (0)
Hint
Help VideoCorrect
Well Done!
Incorrect
Rules for Multiplying Integers
First, plug in the given values`x=6`
`y=-5``-3+3``x``+3``y` `=` `-3+3(``6``)+3(``-5``)` Next, solve the multiplication.`-3+``(3)(6)` `+3(-5)` `=` `-3+``18` `-15` Recall, Now, solve the equationKeep in mind the rules for adding integers.`-3+18` `-15` `=` `15` `-15` `=` `0` `0`
