-2x+9y=5

substitute x=11

-2(11) + 9y =5

-22 +9y =5

add 22 to each side

22-22 +9y =5+22

9y = 27

divide each side by 9

9y/9 = 27/9

y =3

Replace all the x's in the equation with 11.

-2(11)+9y=5

Multiply -2 times 11

-22+9y=5

Then add 22 to both sides of the equation.

9y=27

Then divide both sides by 9.

So you get y=3.
