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 6a + 8a = -7a + x - 6 for a in terms of x.
| 2\(\frac{1}{7}\)x + \(\frac{2}{7}\) | |
| -\(\frac{4}{5}\)x - 1\(\frac{2}{5}\) | |
| -\(\frac{7}{13}\)x - \(\frac{6}{13}\) | |
| \(\frac{1}{3}\)x + \(\frac{5}{9}\) |
