What strategies can be used to solve and equation algebraically?
Use 5x - 12 = 4 - 3x and 3/4x + 10 = 7 as an example.
Please describe each strategy for me, I really don't know how to explain it and my math homework is driving me crazy!!

Step 1: Group variables on one side, constants on the other.
Step 2: "Normalize" variables (in other words, multiply both sides by a factor such that the coefficient of the variable becomes 1).
Example: $\displaystyle \frac{2}{3}x - 1 = 2$
Step 1: $\displaystyle \frac{2}{3}x = 3$
Step 2: $\displaystyle \frac{2}{3}x*(\frac{3}{2}) = 3*(\frac{3}{2})$
Answer: $\displaystyle x = \frac{9}{2}$
Now try your problems.
