Question

PLEASE SOLVE!! Just find the value for x on each labeled problem. Your help is greatly appreciated.

Answer 1

1. x = 4

2. x = 8

3. x = 9

4. x = 7

5. x = -7

6. x = 5

Explanation:

1. 21x + 6 = 90

21x = 90 - 6

x = 84/21 = 4

2. 8x - 4 = 60

8x = 60 + 4

x = 64/8 = 8

3. -1 + 14x = 12x + 17

14x - 12x = 1 + 17

2x = 18

x = 18/2 = 9

4. 75 = 11x - 2

11x = 75 + 2

11x = 77

x = 77/11 = 7

5. x + 139 = 132

x = 132 - 139

x = -7

6. 23x - 5 = 21x + 5

23x - 21x = 5 + 5

2x = 10

x = 10/2 = 5
