Simplifying

5x + y = 120

Solving

5x + y = 120

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

5x + y + - 1y = 120 + - 1y

Combine like terms: y + - 1y = 0

5x + 0 = 120 + - 1y

5x = 120 + - 1y

Divide each side by '5'.

x = 24 + - 0.2y

Simplifying

x = 24 + - 0.2y
