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 + 9c = 2c - 6y - 5 for c in terms of y.
| \(\frac{2}{13}\)y - \(\frac{2}{13}\) | |
| -2\(\frac{1}{2}\)y - \(\frac{5}{6}\) | |
| \(\frac{1}{9}\)y + \(\frac{1}{3}\) | |
| -y - \(\frac{1}{2}\) |
