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 = -4c + 6y + 6 for c in terms of y.
| y + 3 | |
| 2\(\frac{1}{7}\)y + \(\frac{6}{7}\) | |
| y + \(\frac{2}{5}\) | |
| 1\(\frac{4}{11}\)y - \(\frac{5}{11}\) |
