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 -2a - 9a = -a + 7x + 6 for a in terms of x.
| -\(\frac{1}{5}\)x - \(\frac{3}{5}\) | |
| \(\frac{2}{5}\)x - 1 | |
| 1\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| -16x - 6 |
