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 -3a - 8a = 9a - 7x - 2 for a in terms of x.
| -\(\frac{4}{11}\)x + \(\frac{8}{11}\) | |
| \(\frac{7}{18}\)x + \(\frac{1}{18}\) | |
| \(\frac{7}{10}\)x + \(\frac{2}{5}\) | |
| -\(\frac{1}{12}\)x + \(\frac{1}{6}\) |
