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 9c + 7c = -2c - x - 5 for c in terms of x.
| \(\frac{1}{2}\)x + \(\frac{3}{8}\) | |
| -1\(\frac{1}{4}\)x - 2\(\frac{1}{4}\) | |
| -\(\frac{8}{11}\)x - \(\frac{5}{11}\) | |
| x - \(\frac{6}{7}\) |
