Answer:

9) e=-40 10) k=9

Step-by-step explanation:

9) e/4-10=-20  add 10 on both sides

e/4=-10  Multiply everything by 4

e=-40

10) 0.4k-4+1.6k=14   combine like terms

2k-4=14   Add 4 on both sides

2k=18   divide both sides by 2

k=9

Which of the following BEST describes how to use the addition property of equality to isolate the variable y
Alexandra [31]

Answer:  C) add 12 to both sides

Reason:

We add 12 to the left side to undo the -12, which will get y by itself.

We must do the same thing to both sides to keep things balanced.
