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 - 9c = -4c - 7y - 6 for c in terms of y.
| -y + 3 | |
| \(\frac{2}{9}\)y + \(\frac{8}{9}\) | |
| -4y - 9 | |
| \(\frac{1}{2}\)y + 4 |
