    Simplifying 8x + - 6y = - 20

    Solving 8x + - 6y = - 20

    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. 8x + - 6y + 6y = - 20 + 6y

    Combine like terms: - 6y + 6y = 0 8x + 0 = - 20 + 6y 8x = - 20 + 6y

    Divide each side by '8'. x = - 2.5 + 0.75y

    Simplifying x = - 2.5 + 0.75y
