Answer:
you can check your solution by substituting your answer for y
y = -4.5
Step-by-step explanation:
18 = -4y
to isolate y, divide both sides by -4:
[tex]\frac{18}{-4} = \frac{-4y}{-4}[/tex]
-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
