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 - 8a = -6a - 2x + 5 for a in terms of x.
| \(\frac{2}{5}\)x + \(\frac{1}{3}\) | |
| x - 9 | |
| 2\(\frac{3}{5}\)x - \(\frac{2}{5}\) | |
| -\(\frac{11}{12}\)x - \(\frac{1}{4}\) |
