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 -4c - 2c = 9c - y + 3 for c in terms of y.
| \(\frac{1}{9}\)y + \(\frac{2}{3}\) | |
| -\(\frac{1}{13}\)y - \(\frac{3}{13}\) | |
| -\(\frac{1}{4}\)y - \(\frac{3}{4}\) | |
| 17y + 4 |
