Question

Помогите решить
8x+3(7-2x)=4x+3
23-4(3x+8)=1-17x

Answer 1

8x+3(7-2x)=4x+3
8х+21-6х=4х+3
8х-6х-4х=3-21
-2х=-17
х=-8,5
23-4(3x+8)=1-17x
23-12х-32=1-17х
-12х+17х=1-23+32
5х=10
х=2

Answer 2

3-21=-18 (в первом уравнении)

Answer 3

1.
8х+3(7-2х)=4х+3
8х+21-6х=4х+3
8х-6х-4х=3-21
-2х=-18
2х=18
х=18:2
х=9

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