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 = -4c - 7y + 8 for c in terms of y.
| 3\(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
| -\(\frac{10}{17}\)y - \(\frac{1}{17}\) | |
| 1\(\frac{1}{2}\)y - 2 | |
| -\(\frac{1}{3}\)y - \(\frac{2}{3}\) |
