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 - 2c = -9c + 4y + 1 for c in terms of y.
| 1\(\frac{7}{8}\)y - \(\frac{1}{4}\) | |
| \(\frac{1}{3}\)y + \(\frac{1}{18}\) | |
| -5\(\frac{2}{3}\)y - 2\(\frac{2}{3}\) | |
| 1\(\frac{4}{9}\)y + \(\frac{1}{3}\) |
