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