2x+3y=6<span>Simplifying
2x + 3y = 6
Solving
2x + 3y = 6
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.
2x + 3y + -3y = 6 + -3y
Combine like terms: 3y + -3y = 0
2x + 0 = 6 + -3y
2x = 6 + -3y
Divide each side by '2'.
x = 3 + -1.5y
Simplifying
x = 3 + -1.5y
