    Steps:I will try to solve your system of equations.

    y = - 8x + 23; - 7x + 2y = - 23

    Step: Solve y = - 8x + 23 for y: Step:

    Substitute - 8x + 23 for y in - 7x + 2y = - 23:

    - 7x + 2y = - 23 - 7x + 2 ( - 8x + 23) = - 23 - 23x + 46 = - 23 (Simplify both sides of the equation) - 23x + 46 + - 46 = - 23 + - 46 (Add - 46 to both sides) - 23x = - 69 - 23x - 23 = - 69 - 23 (Divide both sides by - 23) x=3 Step: Substitute 3 for x in y = - 8x + 23 : y = - 8x + 23 y = (-8) (3) + 23 y = - 1 (Simplify both sides of the equation)

    Answer: y = - 1 and x = 3
