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 3c + 9c = -c + 2y - 6 for c in terms of y.
| \(\frac{9}{17}\)y - \(\frac{2}{17}\) | |
| -1\(\frac{3}{4}\)y - 1\(\frac{1}{2}\) | |
| -y + 1\(\frac{2}{5}\) | |
| 1\(\frac{4}{7}\)y - \(\frac{5}{7}\) |
