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 - 9c = 6c - 2y - 8 for c in terms of y.
| -1\(\frac{1}{3}\)y + 2\(\frac{2}{3}\) | |
| -11y - 7 | |
| \(\frac{1}{2}\)y - \(\frac{1}{14}\) | |
| 7y - 8 |
