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