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 + 8c = 3c + 9y + 3 for c in terms of y.
| \(\frac{1}{13}\)y + \(\frac{6}{13}\) | |
| -\(\frac{1}{12}\)y - \(\frac{1}{4}\) | |
| -1\(\frac{6}{7}\)y + \(\frac{1}{7}\) | |
| -\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) |
