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 + c = -4c - 4y - 1 for c in terms of y.
| -\(\frac{2}{7}\)y + \(\frac{2}{7}\) | |
| -14y - 4 | |
| \(\frac{6}{7}\)y + \(\frac{2}{7}\) | |
| -\(\frac{5}{13}\)y - \(\frac{1}{13}\) |
