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 6c + 2c = -9c - 7y - 7 for c in terms of y.
| -17y + 2 | |
| -\(\frac{3}{5}\)y - \(\frac{7}{15}\) | |
| -7y - 4\(\frac{1}{2}\) | |
| -1\(\frac{2}{5}\)y + 1\(\frac{3}{5}\) |
