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 + 5c = -c - 7y + 5 for c in terms of y.
| -1\(\frac{1}{2}\)y + \(\frac{3}{4}\) | |
| 1\(\frac{1}{2}\)y + 4\(\frac{1}{2}\) | |
| \(\frac{7}{8}\)y + \(\frac{1}{8}\) | |
| -1\(\frac{1}{5}\)y + \(\frac{1}{2}\) |
