26-(7-2x)=5x 26 - 7 + 2x = 5x 19 + 2x = 5x 2x - 5x = -19 -3x = - 19 x = -19 : (-3) x = 19/3 = 6 1/3 19-2(3x+18)=2x-37 19 - 6x - 36 = 2x - 37 -17 - 6x = 2x - 37 -6x - 2x = -37 + 17 -8x = - 20 x = - 20 : (-8) x =  2,5 23-4(3x+8)=1-17x 23 - 12x - 32 = 1 - 17x -9 - 12x = 1 - 17x -12x + 17x = 1 +9 5x = 10 x = 10:5 x = 2
