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 -5c - 6c = -2c + 9y + 9 for c in terms of y.
| -5y - 3 | |
| 4y + 5 | |
| 12y + 4 | |
| \(\frac{6}{11}\)y - \(\frac{8}{11}\) |
