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 = -5c - 4y + 9 for c in terms of y.
| y + \(\frac{3}{4}\) | |
| -\(\frac{7}{12}\)y + \(\frac{2}{3}\) | |
| -1\(\frac{1}{2}\)y + 4\(\frac{1}{2}\) | |
| -\(\frac{5}{6}\)y - 1\(\frac{1}{3}\) |
