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 - 7c = -7c + 9y - 5 for c in terms of y.
| \(\frac{4}{9}\)y - \(\frac{4}{9}\) | |
| -\(\frac{1}{12}\)y - \(\frac{1}{2}\) | |
| \(\frac{1}{7}\)y - \(\frac{4}{7}\) | |
| 16y - 5 |
