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