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