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 - 3c = 4c - 4y + 3 for c in terms of y.
| -6y - 9 | |
| -\(\frac{1}{2}\)y + 1\(\frac{1}{2}\) | |
| -7y + 4\(\frac{1}{2}\) | |
| \(\frac{1}{2}\)y - 1 |
