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 -7c - 7c = 8c - 2y - 9 for c in terms of y.
| \(\frac{1}{17}\)y - \(\frac{7}{17}\) | |
| 1\(\frac{1}{2}\)y + \(\frac{7}{8}\) | |
| \(\frac{16}{17}\)y + \(\frac{2}{17}\) | |
| -\(\frac{1}{3}\)y + \(\frac{3}{5}\) |
