Algebra pomocy!!! Wykonaj działania (-x-2)*(-2)=10 7(x-8)-56=12 -(x+5)+10=2y 4x+5=6x-7

(-x-2)*(-2)=10 2x + 4 = 10 2x = 10 - 4 = 6 x = 6/2 = 3 7(x-8)-56=12 7x - 56 - 56 = 12 7x = 112 x = 112/7 = 16 -(x+5)+10=2y 2y = - x - 5 + 10 2y = - x + 5 2y + x = 5 4x+5=6x-7 4x - 6x = - 7 - 5 - 2x = - 12 x = 12/2 = 6
