Simplifying

3x + 3y = -3

Solving

3x + 3y = -3

Solving for variable 'x'.

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

Add '-3y' to each side of the equation.

3x + 3y + -3y = -3 + -3y

Combine like terms: 3y + -3y = 0

3x + 0 = -3 + -3y

3x = -3 + -3y

Divide each side by '3'.

x = -1 + -1y

Simplifying

x = -1 + -1y
