Question

Solve for y when x =0
-9x-2y=-20

Answer 1

10

substitute 0 for x in the equation.

-9(0) - 2y= -20

0 - 2y = -20

-2y= -20 (divide by -2)

y = 10

Answer 2

-9x - 2y = -20, x = 0

Plug in 0 for x.

-9(0) - 2y = -20

Simplify.

0 - 2y = -20

-2y = -20

Divide both sides by -2.

y = -20/-2

Simplify.

y = 10
