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 10c + 7c = 9c - 6x - 1 for c in terms of x.
| -6x - 9 | |
| -\(\frac{1}{11}\)x - \(\frac{4}{11}\) | |
| -\(\frac{5}{6}\)x - \(\frac{1}{6}\) | |
| -13x - 1 |
