no entendí casi esto me ayudan

Answer 1

Respuesta:

1 .2x - 34 = -20

2x = -20+34

2x = 14

x = 14/2

x= 7

2. 9x + 8 = 7x +6

9x - 7x = -8+6

2x = 2

x = 2/2

x = -1

3. 4x + 3 = 3x + 5

4x - 3x = 5 - 3

x = 2

4 . 7x + 9 = 3 + 9x

7x - 9x = 3 - 9

-2x = -6

x = -6/-2

x= 3

5. x - 8 = 2x -11

x - 2x = -11 + 8

-x = -3

6. x + 1 = 2x + 7

x - 2x = 7 - 1

x = 6
