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 -4c - 6c = -9c - 8y - 8 for c in terms of y.
| -\(\frac{2}{5}\)y - 1\(\frac{3}{5}\) | |
| -1\(\frac{2}{3}\)y + 2\(\frac{1}{3}\) | |
| \(\frac{3}{4}\)y - \(\frac{1}{2}\) | |
| 2y + 7 |
