Answer 1

Explicación paso a paso:

• 8x + 9 - 12x = 4x - 13 - 5x

8x - 12x - 4x + 5x = - 13 - 9

-3x = -22

x = -22/-3

x = 7.333

• 16 + 7b - 5 + b = 11b - 3 - b

7b + b - 11b + b = -3 + 5 - 16

-2b = -14

b = -14/-2

b = 7

• 3m + 101 - 4m - 33 = 108 - 16m - 100

3m - 4m + 16m = 108 - 100 - 101 + 33

15m = -60

m = -60/15

• 14 - 2a + 39a - 18a = 256 - 60a - 657a

-2a + 39a - 18a + 60a + 657a = 256 - 14

736a = 242

a = 242/736

a = 0.328

• 5y + 6y - 81 = 7y + 102 + 65y

5y + 6y - 7y - 65y = 102 + 81

-61y = 183

y = 183/-61

y = -3
