Equations w/ Variable on Both Sides
Solve.
1. 8x = x + 14
2. 11 – 4x = 7x – 22
x = 2
3. 5b – 2 = b + 10
b = 3
5. 13x + 8 + 8x = -9x – 22
x = -1
x = 3
4. -7r – 8 = -5r + 4
r = -6
6. 7x – 11 = -19 + 3x
x = -2
8. 4(3d – 2) = 8d – 24
7. 15y – 8 = 2(5y +6)
y = 4
d = -4
10. -2(5h – 6) = -2(9 + 4h) – 2h
9. 8(m + 2) = 4(2m + 4)
