1/3(3х-1/2)-(1/3-1/4х)=-2(1/2х-5)x - 1/6 - 1/3 + 1/4x = -x + 101 1/4x - 1/2 = -x + 101 1/4x + x = 10 + 1/22 1/4x = 10 1/2x = 10 1/2 : 2 1/4x = 21/2 * 4/9x = 14/3x = 4 2/3-4(2х-1)-(х-3)-4(-х-3)=-3(3х-4)-8x + 4 - x + 3 + 4x + 12 = -9x + 12-5x + 19 = -9x + 12-5x + 9x = 12 - 194x = -7x = -7:4x = -1,75...
