Question

To solve the equation, 18 = -4y, you use the division property of equality and simplify. Explain how can you check your solution.

Answer 1

you can check your solution by substituting your answer for y

y = -4.5

Explanation:

18 = -4y

to isolate y, divide both sides by -4:

`(18)/(-4) = (-4y)/(-4)`

-4.5 = y

to check if anser is right, substitute -4.5 for y, make sure the ending results equals each other:

18 = -4y

18 = -4 (-4.5)

18 = 18
