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 -9c + 7c = -8c - y + 7 for c in terms of y.
| 8y - 7 | |
| -\(\frac{4}{11}\)y + \(\frac{2}{11}\) | |
| \(\frac{13}{16}\)y - \(\frac{1}{2}\) | |
| \(\frac{5}{6}\)y + \(\frac{1}{2}\) |
