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 -9c + 9c = -5c + 3y + 3 for c in terms of y.
| 1\(\frac{6}{7}\)y - 1\(\frac{2}{7}\) | |
| \(\frac{1}{2}\)y - 3\(\frac{1}{2}\) | |
| 1\(\frac{1}{3}\)y - 2\(\frac{2}{3}\) | |
| 1\(\frac{1}{2}\)y - \(\frac{3}{4}\) |
