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 2c + 9c = -5c + 7y - 9 for c in terms of y.
| -\(\frac{2}{7}\)y - 1\(\frac{2}{7}\) | |
| -\(\frac{1}{3}\)y - \(\frac{5}{12}\) | |
| 9y + 6 | |
| \(\frac{3}{5}\)y + \(\frac{1}{15}\) |
