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