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