4 ( 13 — 3x ) —17 = — 5х Помогите решить эти 2 уравнения ( 18 — 3x ) — ( 4 + 2x ) = 10

1) 4(13-3x)-17=-5x 52-12x-17+5x=0 35-7x=0 7x=35|:7 x=5 2) (18-3x)-(4+2x)=10 14-5x=10 14-10-5x=0 4-5x=0 5x=4|:5 x=0,8

4(13-3х)-17 = -5х                            (18-3х)-(4+2х) = 10 52-12х-17 = -5х                               18-3х-4-2х = 10 5х-12х = 17-52                                 -3х-2х = 10-18+4 -7х = -35                                            -5х = -4 х = -35:(-7)                                          х = -4:(-5) х=5                                                     х=0,8
