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 - 2c = 4c + 5y - 8 for c in terms of y.
| -y - 2 | |
| -2\(\frac{1}{3}\)y + 2\(\frac{2}{3}\) | |
| \(\frac{1}{2}\)y + \(\frac{9}{10}\) | |
| -y - 2\(\frac{2}{3}\) |
