Equations cannot always be solved in one step. sometimes you must perform several operations before you can solve for the variable. you must try to isolate the variable on one side of the equation (usually the left).
example:
2x + 4 = 12 first, subtract 4 from each side
2x = 8
then divide each side by 2
x = 4
the solution (answer) is 4
example:
1/3s - 6 = 18
first, add 6 to each side
1/3s = 24
then, multiply each side by 3 (inverse of 1/3)
s = 72
the solution (answer) is 72

lesson review
directions: solve each of the following equations.
1. 2x - 12 = 6
2. 2x + 6= 8
3. 12s - 12=12
4. 14s + 6 = 35
5. 3s - 12 = 6
6. 18t + 9 = 34
7. 21x + 7 = 28
8. 50y + 5 = 105
9. 1/4x - 6 = 24
10. 13x + 2 = 18
11. 6 - 3x = 18
12. 14 + s = 21
13. 16x - 4 = 28
14. 19x - 1 + 3 = 40
15. 10t = 194
16. 400x + 100 = 1100
17. 40 - 3x + 3 = 113
