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