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 3c - 3c = -4c + 2x - 7 for c in terms of x.
| -\(\frac{8}{13}\)x - \(\frac{3}{13}\) | |
| -\(\frac{1}{2}\)x + \(\frac{3}{5}\) | |
| -\(\frac{1}{14}\)x + \(\frac{1}{14}\) | |
| \(\frac{5}{7}\)x - 1 |
