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