Question

Решите уравнение
19-2(3х+8)=2х-37
23-4(3х+8)=1-17х

Answer 1

19-2(3х+8)=2х-37
19-6x+16=2x-37
-6x-2x=-37-19
-8x=-56
x=7

23-4(3x+8)=1-17x
23-12x-32=1-17x
-12x+17x=1-23+32
5x=10
x=2

Answer 2

19-2(3х+8)=2х-37
19-6х-16=2х-37
-6х-2х=-37-19+16
-8х=-40
х=-40/(-8)
х=5

23-4(3х+8)=1-17х
23-12х-32=1-17х
-12х+17х=1-23+32
5х=10
х=10/5
х=2
