When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 3a - 3a = a - x - 4 for a in terms of x.
| -\(\frac{1}{4}\)x + 1\(\frac{1}{8}\) | |
| x - 2 | |
| -2x - 1\(\frac{1}{2}\) | |
| 1\(\frac{1}{12}\)x + \(\frac{1}{2}\) |
