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 - 4c = -8c + y - 9 for c in terms of y.
| \(\frac{15}{16}\)y + \(\frac{1}{8}\) | |
| y - 1\(\frac{4}{5}\) | |
| \(\frac{5}{17}\)y - \(\frac{9}{17}\) | |
| 14y - 4 |
