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 5c + 2c = c + y - 9 for c in terms of y.
| \(\frac{5}{12}\)y - \(\frac{1}{4}\) | |
| -13y - 7 | |
| -\(\frac{1}{4}\)y - 2\(\frac{1}{4}\) | |
| \(\frac{2}{3}\)y - \(\frac{1}{2}\) |
