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