5y - 10 = -25 a) y = 3 b) y = 7 c) y = -3 d) y = -7

Hi there!

C. y=-3

Step-by-step explanation:

5y-10=-25

add by 10 both sides of an equation.

5y-10+10=-25+10

simplify.

5y=-15

divide by 5 both sides of an equation.

5y/5=-15/5

simplify.

-15/5=-3

15/5=3

15/3=5

3*5=15

5*3=15

y=-3

Hope this helps!

Have a great day!

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
