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

1) 4(13-3x)-17=-5x52-12x-17+5x=035-7x=07x=35|:7x=52) (18-3x)-(4+2x)=1014-5x=1014-10-5x=04-5x=05x=4|:5x=0,8

4(13-3х)-17 = -5х                            (18-3х)-(4+2х) = 1052-12х-17 = -5х                               18-3х-4-2х = 105х-12х = 17-52                                 -3х-2х = 10-18+4-7х = -35                                            -5х = -4х = -35:(-7)                                          х = -4:(-5)х=5                                                     х=0,8
