Complete the solution of the equation Find the value of y when x equals 11. 7x-9y=23

Replace the variable x with it's value in the equation and solve for y.

7 (11) - 9y = 23

77 - 9y = 23

Subtract both sides by 77.

77 - 9y - 77 = 23 - 77

-9y = - 54

Divide both sides by - 9.

-9y / - 9 = - 54 / - 9

y = 6

So, 6 is the answer.
