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 - 5c = c + 4y + 2 for c in terms of y.
| \(\frac{2}{13}\)y - \(\frac{9}{13}\) | |
| -\(\frac{9}{10}\)y - \(\frac{1}{5}\) | |
| -\(\frac{1}{7}\)y - \(\frac{2}{7}\) | |
| -4\(\frac{2}{3}\)y + \(\frac{1}{3}\) |
