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 9a - 9a = -a + 5x + 3 for a in terms of x.
| 1\(\frac{2}{5}\)x + \(\frac{3}{10}\) | |
| x - 1\(\frac{1}{6}\) | |
| -\(\frac{1}{4}\)x - \(\frac{1}{12}\) | |
| \(\frac{1}{5}\)x - 1\(\frac{2}{5}\) |
