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 - 5c = 6c - 5y + 9 for c in terms of y.
| y - 3 | |
| -y + \(\frac{4}{13}\) | |
| 3\(\frac{1}{4}\)y - 1\(\frac{3}{4}\) | |
| -1\(\frac{1}{2}\)y - \(\frac{1}{4}\) |
