Answer 1

Explicación paso a paso:

1) 6m - 31 = 2m - 7

6 m - 2 m = -7 + 31

4m = 24

m = 24/4

m = 6

2) 3x + 27 = 5x + 37

3x - 5x = 37 - 27

- 2x = 10

x = 10/-2

x = - 5

3) 4r - 9r - 2 = 7r - 5r - 9

4r - 9r - 7r + 5r = 2 - 9

9r - 16r = -7

- 7r = - 7

r = -7/-7

r = 1

4) 5y + 1 = 2(y + 44)

5y + 1 = 2y + 88

5y - 2y = 88 - 1

3y = 87

y = 87/3

y = 29

5) 4(2x + 5) = 12

8x + 20 = 12

8x = 12 - 20

8x = - 8

x = -8/8

x = -1

6) 3w + (w + 5) = 5w - (3 + 2w)

3w + w + 5 = 5w -3 - 2w

3w + w - 5w + 2w = - 3 - 5

6w - 5w = - 8

w = - 8

7) p + 7 (p + 3) = 2p + 75

P + 7 p + 21 = 2 P + 75

P + 7p - 2p = 75 - 21

6p = 54

P = 54/6

P = 9
