Question

160x+560=-160(3x-1)

Answer 1

160x+560=-160(3x-1),160х +560 = - 480х +160,
160х + 480х = 160 - 560,
640х = - 400
х = ( - 400): 640
х = - 5/8
х= - 0,625

Answer 2

160x+560=160-480x
640x=-400
80*8x=80*(-5)
8x=-5
x= -5/8

Answer 3

160x+560=-160(3x-1)
160х +560 = - 480х +160
160х + 480х = 160 - 560
640х = - 400
х =  - 400: 640
х = - 5/8
х= - 0,625
