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 + 9c = -4c + 4y - 1 for c in terms of y.
| \(\frac{1}{9}\)y - \(\frac{8}{9}\) | |
| 7y + 4 | |
| -\(\frac{5}{9}\)y - \(\frac{1}{9}\) | |
| -\(\frac{1}{2}\)y - 2 |
