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 -5a + 5a = -2a - 3x + 7 for a in terms of x.
| 12x + 1 | |
| -\(\frac{1}{8}\)x - \(\frac{1}{4}\) | |
| 1\(\frac{3}{4}\)x + \(\frac{5}{8}\) | |
| 2\(\frac{2}{3}\)x - 2\(\frac{1}{3}\) |
