-3(y-50)=24<br><br> Plz help -sob-
Leni [432]

<u><em>Answer: y=42</em></u>

Step-by-step explanation:

division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

-3(y-50)/-3=24/-3

simplify.

y-50=-8

add 50 both sides of an equation.

y-50+50=-8+50

simplify.

-8+50=42

50-8=42

42+8=50

y=42

Hope this helps!

Thanks!

Have a great day!
