Question

Solve the following equations:

16 + x = 31
0 = -18x
x/17 = -4
14 = v/16 -23
84 = -12x
280 = 20k
6x + 7 + 2x = -9
3a - 5a = -4
8n + 8n = 16
2x - 3 + 5 = 12
14 = -6k - 8k
-112 = 8 + 2(-8a-4)
3(5n - 3) = 81
7(p + 3) + 5 = 82
-188 = -6(2 - 3a) + 4a

Answer 1

To solve each equation, isolate the variable by performing the necessary operations on both sides of the equation.

Step-by-step explanation:

To solve the given equations:

1. 16 + x = 31
2. 0 = -18x
3. x/17 = -4
4. 14 = v/16 -23
5. 84 = -12x
6. 280 = 20k
7. 6x + 7 + 2x = -9
8. 3a - 5a = -4
9. 8n + 8n = 16
10. 2x - 3 + 5 = 12
11. 14 = -6k - 8k
12. -112 = 8 + 2(-8a-4)
13. 3(5n - 3) = 81
14. 7(p + 3) + 5 = 82
15. -188 = -6(2 - 3a) + 4a

The solutions to the equations are as follows:

1. x = 15
2. x = 0
3. x = -68
4. v = 89
5. x = -7
6. k = 14
7. x = -4
8. a = 2
9. n = 1
10. x = 10
11. k = -1
12. a = 4
13. n = 6
14. p = 7
15. a = -5
