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 -9c - 7c = 6c - 7y - 9 for c in terms of y.
| y + \(\frac{3}{5}\) | |
| 4\(\frac{1}{2}\)y - 3\(\frac{1}{2}\) | |
| y + \(\frac{3}{13}\) | |
| \(\frac{1}{6}\)y - 1\(\frac{1}{2}\) |
