Answer:
Simplifying
9 + -3x = y
Solving
9 + -3x = y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + -3x = -9 + y
Combine like terms: 9 + -9 = 0
0 + -3x = -9 + y
-3x = -9 + y
Divide each side by '-3'.
x = 3 + -0.3333333333y
Simplifying
x = 3 + -0.3333333333y
