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 8a + 7a = -9a + x - 2 for a in terms of x.
| -1\(\frac{2}{3}\)x - \(\frac{1}{2}\) | |
| \(\frac{12}{13}\)x + \(\frac{4}{13}\) | |
| -\(\frac{6}{17}\)x - \(\frac{2}{17}\) | |
| -\(\frac{5}{7}\)x - \(\frac{3}{7}\) |
