1) 2(-x-1) = 0 => -2x-2 = 0 => -2x = 2 => x = -1 2) 3(-2x+1)=9 => -6x + 3=9 => -6x=9-3 => -6x=6 => x=-1 3)4(3x-3)=12 => 12x-12=12 => 12x=12+12 => 12x=24 => x=2 4)4(25x+25)=200 =>100x+100=200 =>100x=100 =>x=1 5) 3(x-4)=12 => 3x-12=12 => 3x=24 => x=8 6) 5(2x+20)=50 => 10x+100=50 => 10x=-50 => x=-5 7) 2(13x-13)=0 => 26x-26=0 => 26x=26 => x=1 8) 12(2x+1)=60 => 24x+12=60 => 24x=48 => x=2 9) 3(-x-3)=9 => -3x-9=9 => -3x=18 => x=-6 10) 5(5x-5)=50 => 25x-25=50 => 25x=75 => x=3 11) 1(x+2)=0 => x+2=0 => x=-2 12) 9(-9x-9)=0 => -81x-81=0 => -81x=81 => x=-1 13) 2(20x+10)=20 => 40x+20=20 => 40x=0 => x=0 14) 6(2x-1)=6 => 12x-6=6 => 12x=12 => x=1 hope i have been clear in my working & hope i have been of some help to you.
