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 + 3a = -9a - 5x + 3 for a in terms of x.
| 2\(\frac{2}{5}\)x - \(\frac{2}{5}\) | |
| \(\frac{5}{7}\)x + \(\frac{4}{7}\) | |
| -3\(\frac{3}{4}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{4}{9}\)x + \(\frac{1}{6}\) |
