Question

1) 3х-2=6+4х
2) 11+2х=55+3х
3) 5х+(3х-7)=9
4) (7а+1)-(6а+3)=5
5) 6(х-1)=94-17х

Answer 1

Ответ:

1) 3х-2=6+4х

3x-4y=6+2

-x=8

x= -8

2) 11+2х=55+3х

2x-3x=55-11

-x = 44

x= -44

3) 5х+(3х-7)=9

8x=9+7

8x = 16

x = 2

4) (7а+1)-(6а+3)=5

7a-6a=5-1-3

a = 1

5) 6(х-1)=94-17х

6х-6=94-17х

25x = 100

x = 4
