5) x=2

6) x=1

7) x=3

Answer 2

Explicación paso a paso:

1) 5x + 4 = 3x +6

5x-3x = 6-4

2x = 2

x = 2/2

x = 1

2) 7x +3 = 4x + 12

7x-4x = 12-3

3x = 9

x = 9/3

x = 3

3) 6x – 7 = 2x + 5

6x-2x = 5+7

4x = 12

x = 12/4

x = 3

4) 9x – 8 = 5x + 20

9x - 5x=20+8

4x = 28

x = 28/4

x = 7

5) 11x + 5 = 6x +15

11x - 6x=15-5

5x = 10

x = 10/5

x = 2

6) 8x – 6 = 4x – 2

8x - 4x= 6 - 2

4x = 4

x = 4/4

x = 1

7) 9x + 8 = 6x +17

9x-6x = 17-8

3x = 9

x = 9/3

x = 3
