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 8c - c = -8c - 9y - 7 for c in terms of y.
| -7\(\frac{1}{2}\)y + 2 | |
| -11y - 3 | |
| -1\(\frac{2}{5}\)y - \(\frac{3}{5}\) | |
| -\(\frac{1}{2}\)y - \(\frac{7}{16}\) |
