SOLVING EQUATIONS
TIP: When doing these sort of problems, remember:
a) All the
techniques used for rearranging formulae
apply to equations also - though
solving equations is normally much easier.
Solve the following equations:
| 1. ½x + 7 = 4 |
|
2. 2 - 6y = 1
|
| 3. 9 - 2x = 3 - 4x |
| 4. 2 - 7a = 3a |
| 5. 4(x + 3) = 16 |
| 6. 5(x - 4) = 3x - 7 |
| 7. 4(3x - 2) - (7x + 8) = 2(x -5) |
8.  |
