<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.
divide by -3 both sides of an 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!
