Simplifying
3x + 6y = 6

Solving
3x + 6y = 6

Solving for variable 'x'.

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

Add '-6y' to each side of the equation.
3x + 6y + -6y = 6 + -6y

Combine like terms: 6y + -6y = 0
3x + 0 = 6 + -6y
3x = 6 + -6y

Divide each side by '3'.
x = 2 + -2y

Simplifying
x = 2 + -2y
