Question

решите уравнение
8х+3(7-2х)=4х+3
23-4(3х+8)=1-17х

Answer 1

1) 8х+21-6х=4х+3
8х-4х-6х=3-21
-2х=-18
х=9
2)23-12х-32=1-17х
-12х+17х=1-23+32
5х=10
х=2

Answer 2

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

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