  1. Divide the 2 to both sides of the fits equation making a = 4
    then Subsituted the 4 for a in the second equation making it 4+B=2 then subtract the four from both sides making the equation B equels -2

    Solve this system of linear equations. * Used the substitution method 3x - y = 8 4x - y = -15 ----------------------------------------- WORK y = 3x - 8 4x - (3x - 8 ) = -15 4x - 3x + 8 = -15 x + 8 = -15 x = -7 3x - y = 8 3(-7) - y
