solve for x

Question

y = x - 6
y = 9

Answer 1

To solve for x, we have the equations:

1) y = x - 6
2) y = 9

Since both equations are equal to y, we can set them equal to each other:

x - 6 = 9

To isolate x, we can add 6 to both sides of the equation:

x - 6 + 6 = 9 + 6
x = 15

Therefore, x = 15 is the solution.
