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 -c - 4c = -2c - 4y - 2 for c in terms of y.
| -9y + 4 | |
| \(\frac{1}{4}\)y - 1 | |
| -\(\frac{13}{16}\)y + \(\frac{1}{16}\) | |
| y - 2 |
