Question

8x + 27 = 2x - 3
4x + 3 = 3x + 5
9x + 8 = 7x + 6
7x - 12 = 5x + 16
9 + 9x = 17 + 5x
9x + 8 = 7x + 6​

Answer 1

Respuesta:

8x + 27 = 2x - 3

8x - 2x = -3 - 27

6x = -30

X = -30/6

X = -5

4x + 3 = 3x + 5

4x - 3x = 5 - 3

X = 2

9x + 8 = 7x + 6

9x - 7x = 6 - 8

2x = -2

X = -2/2

X = -1

7x - 12 = 5x + 16

7x - 5x = 16 + 12

2x = 28

X = 28/2

X = 14

9 + 9x = 17 + 5x

9x - 5x = 17 - 9

4x = 8

X = 8/4

X = 2

9x + 8 = 7x + 6

9x - 7x = 6 - 8

2x = -2

X = -2/2

X = -1
