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 8c - 8c = 7c - 2x - 7 for c in terms of x.
| x + \(\frac{1}{2}\) | |
| \(\frac{5}{17}\)x - \(\frac{3}{17}\) | |
| -\(\frac{6}{7}\)x - \(\frac{1}{7}\) | |
| 6x - 7 |
