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 -6a - 5a = -9a - 4x + 9 for a in terms of x.
| -\(\frac{1}{4}\)x - \(\frac{1}{12}\) | |
| \(\frac{11}{12}\)x + \(\frac{1}{6}\) | |
| 6x - 8 | |
| \(\frac{1}{3}\)x + 3 |
