Помогите - 27x+600=29x+152. 2) - 3 (5y-7) = 6 (2y+34) + 60 3) 45-5 (12z+3) = 186+3 (3z-6)

600-152=29x+27x

448=56x

X=8

2) - 15y+21=12y+204+60

-15y+21=12y+264

15y+12y=21-264

17y=-234

Y = - 14.3

3) 45-60z-15=186+9z-18

30-60z=168+9z

30-168=60z+9z

138=69z

Z=2

-27x+600=29x+152

-27 х-29 х=152-600

-56 х=-448

56 х=448

х=448/56

х=8

-3 (5y-7) = 6 (2y+34) + 60

-15 у+21=12 у+204+60

-15 у-12 у=264-21

-27 у=243

у=243 / (-27)

у = - 9

45-5 (12z+3) = 186+3 (3z-6)

45-60z-15=186+9z-18

-60z-9z=168-30

-69z=138

z=138 / (-69)

z = - 2
