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