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 -7c - 7c = -9c - 9y - 3 for c in terms of y.
| \(\frac{3}{4}\)y - 2\(\frac{1}{4}\) | |
| \(\frac{3}{5}\)y - \(\frac{2}{5}\) | |
| -y - 1\(\frac{1}{2}\) | |
| 8\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) |
