Okay well, I am a little confused by this equation, but to solve 5x-y=35 you would, here:
Simplifying
5x + -1y = 35
Solving
5x + -1y = 35
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
5x + -1y + y = 35 + y
Combine like terms:
-1y + y = 0
5x + 0 = 35 + y
5x = 35 + y
Divide each side by '5'.
x = 7 + 0.2y
Simplifying
x = 7 + 0.2y
