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 + 8a = -7a + 6x - 8 for a in terms of x.
| -\(\frac{1}{6}\)x - \(\frac{2}{3}\) | |
| -1\(\frac{1}{12}\)x - \(\frac{1}{6}\) | |
| \(\frac{5}{11}\)x - \(\frac{9}{11}\) | |
| 1\(\frac{2}{3}\)x + 3 |
