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 + c = -4c - 7y - 7 for c in terms of y.
| -1\(\frac{1}{7}\)y - 1 | |
| -\(\frac{3}{4}\)y + 1\(\frac{1}{2}\) | |
| -\(\frac{15}{17}\)y - \(\frac{5}{17}\) | |
| y - \(\frac{2}{13}\) |
