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 -5a - 7a = 6a - 2x - 8 for a in terms of x.
| -\(\frac{5}{11}\)x + \(\frac{8}{11}\) | |
| -x + 6 | |
| \(\frac{11}{15}\)x - \(\frac{1}{15}\) | |
| 1\(\frac{2}{5}\)x - 1 |
