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