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 -3c - c = -2c - y - 3 for c in terms of y.
| y + 3 | |
| -\(\frac{4}{5}\)y - 1 | |
| -\(\frac{3}{8}\)y - \(\frac{3}{4}\) | |
| -\(\frac{1}{6}\)y - \(\frac{7}{12}\) |
