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