More solving equations practice!
If you want more practice for tomorrow's quiz, try these!
1. −20 = −4x − 6x
2. 6 = 1 − 2n + 5
3. 8x − 2 = −9 + 7x
4. a + 5 = −5a + 5
5. 4m − 4 = 4m
6. 12 = −4(−6x − 3)
7. 3n − 5 = −8(6 + 5n)
8. −(1 + 7x) − 6(−7 − x) = 36
Answers:
1. x = 2
2. n = 0
3. x = -7
4. a = 0
5. no solution
6. x = 0
7. n = -1
