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