a + 12 = 18 | a = 6 |
k/4 = -8 | k = -32 |
6x = 48 | x = 8 |
1/2d = -10 | d = -20 |
-4x -8 = 20 | x = -7 |
x/3 + 8 = 14 | x = 18 |
8x - 9 = 47 | x = 7 |
12 is equal to 3 more than twice some number | 12 = 2n + 3 |
11 is equal to 5 more than twice some number | 11 = 2n + 5 |
16 is equal to 4 more than three times some number | 16 = 3n + 4 |
20 + 5w = 50 | w = 6 |
8a - 16 = 5a + 8 | a = 8 |
5x - 2 = 3x + 4 | x = 3 |
6 (a - 4) = -12 | a = 2 |
4 ( x - 3) = 20 | x = 8 |
3a - 2a - 8 - 9 = -10 | a = 7 |
4x + 12 - 2 = 6 | x = -1 |
