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