Question

1) 2(x - 3) = 5 - (x + 1)
2) 4x - 6 = 18
3) 5.r - 20 = 3x - 8
4) 32 - 4x = 8
5) 2.x - 5 = 11
6) x + 2 = 14
7) X-5 = 12
8) 3.x = 9
xfa me ayudan ​

Answer 1

Respuesta:

1 ) 2x + x = 5 - 5 + 6

3x = 6

x = 6 / 3

x = 2

2 ) 4x = 18 + 6

4x = 24

x = 24 / 4

x = 6

3 ) 5r - 3x = - 8 + 20

5r - 3x = 12

x = - 12 / 3

x = - 4

5r = 12 + 4

5r = 16

r = 3.2

16 - 4 = 12

4 ) - 4x = 8 - 32

- 4x = - 24

x = - 24 / - 4

x = 6

5 ) 2x = 11 + 5

2x = 16

x = 16 / 2

x = 8

6 ) x = 14 - 2

x = 12

7 ) x = 12 + 5

x = 17

8 ) 3x = 9

x = 9 / 3

x = 3
