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 = 5a - 8x + 9 for a in terms of x.
| 1\(\frac{2}{5}\)x - \(\frac{3}{5}\) | |
| -x - \(\frac{3}{11}\) | |
| \(\frac{3}{14}\)x - \(\frac{9}{14}\) | |
| -\(\frac{4}{5}\)x + \(\frac{2}{5}\) |
