Answer 1

Respuesta:

Explicación paso a paso:

1.

2x/3 +  12 + 4x/9 - 6 = 90

2x/3 + 4x/9 = 90 - 12 - 6

6x/9 + 4x/9 = 90 - 6

10x/9 = 84

10x = (84)(9)

10x = 756

x = 756/10

x = 75.6

2.

2x - 5 + 9x + 8 = 180

2x + 9x = 180 + 5 - 8

11x = 180 - 3

11x = 177

x = 177/11

3.

8x - 4 + 3x/4 + 5 = 180

8x + 3x/4 = 180 + 4 - 5

32x/4 + 3x/4 = 180 -1

35x/4 = 179

35x = (179)(4)

35x = 716

x = 716/ 35

4.

x/4 - 2 +  4x + 2 = 90

x/4 + 4x = 90 +2 - 2

x/4 + 16x/4 = 90

17x/4 = 90

17x = (90)(4)

17x = 360

x = 360/17
