1). (5х-4)+27=123 2). 179-(4у+19)=60 3). (2х-17)-19=44 4). 2*(6х-14)=92 помогите решить уравнения.

(5х -4) + 27 = 123 5х -4 +27 = 123 5х +23 = 123 5х= 123-23 5х=100 х=100:5 х=20 (5*20-4)+27 = 123 (100-4) +27= 123 96+27=123 123=123 179 - (4у +19) = 60 179 - 4у  - 19  = 60 160 - 4у =60 4у= 160 - 60 4у=100 у=100:4 у=25 179 - (4*25 + 19) = 60 179 -  119 = 60 60=60 (2х-17) - 19 = 44 2х - 17 - 19 = 44 2х -36 = 44 2х=44+36 2х= 80 х=80: 2 х = 40 (2*40  -17) - 19 =44 63 - 19 = 44 44=44 2(6х-14)=92 12х - 28 = 92 12х = 92+28 12х = 120 х=120 : 12 х=10 2*(6*10 - 14) = 92 2* 46 =92 92=92
