    x = 40 + - 1.5y

    Step-by-step explanation:

    Simplifying

    2x + 3y = 80

    Solving

    2x + 3y = 80

    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 = 80 + - 3y

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

    2x + 0 = 80 + - 3y

    2x = 80 + - 3y

    Divide each side by '2'.

    x = 40 + - 1.5y

    Simplifying

    x = 40 + - 1.5y
