(2х-4):(-1/3)=-7

у:3 2/9=-7

(2х-4):(-1/3)=-72х-4=-7*(-1\3)2х-4=7\32х=7\3+42х=4 7\32х=6 1\3х=19\3:2х=19\3*1\2х=19\6х=3 1\6у:3 2/9=-7у=-7*3 2\9у=-7*29\9у=-203\9у=-22 5\9

2X - 4 = - 7 * ( - 1/3 ) 2X - 4 = + 7/3 2X = 7/3 + 12/3 = 19/3 X = 19/3 : 2 = 19/6 = 3 1/6 ================================Y = - 7 * 3 2/9 Y = ( - 7/1 * 29/9 )Y = ( - 203/9 )Y = ( - 22 5/9 )===================================
