The division property of equality could be used to solve which of the following equations: 5x=30 x+3=7 (x+2)(x-2)=0 x/4=16

5x=30
And
x/4=16

The rule states that you must divide each side by a non zero number.

So for 5x=30, divide both sides by 5 to get x=6

For x/4=16, divide both sides by 0.25 to get x=64

PS if your homework only requires one answer then choose 5x=30

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
