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