    Simplifying

    2x + 3y = 12


    Solving

    2x + 3y = 12


    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 = 12 + -3y


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

    2x + 0 = 12 + -3y

    2x = 12 + -3y


    Divide each side by ‘2’.

    x = 6 + -1.5y


    Simplifying

    x = 6 + -1.5y
