Question

2x + 5y + 30 = 0 The point ( 5/2 , y) is a solution to the equation shown. What is the value of y? A) -7 B) -5 C) 0 D) 5

Answer 1

A) -7

Explanation:

2x + 5y + 30 = 0

Let x = 5/2

Substitute into the equation

2(5/2) +5y +30 =0

5+5y+30=0

Combine like terms

35 +5y =0

Subtract 35 from each side

35-35 +5y = -35

5y=-35

Divide by 5

5y/5=-35/5

y = -7
