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 = -8c - 7y + 4 for c in terms of y.
| -1\(\frac{3}{7}\)y + 1\(\frac{1}{7}\) | |
| -\(\frac{1}{15}\)y - \(\frac{1}{5}\) | |
| -\(\frac{1}{4}\)y + \(\frac{1}{3}\) | |
| -y + \(\frac{2}{3}\) |
