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 4c + 8c = 2c + 9y + 6 for c in terms of y.
| 1\(\frac{2}{9}\)y + \(\frac{2}{9}\) | |
| \(\frac{1}{2}\)y + 3 | |
| \(\frac{4}{5}\)y - \(\frac{2}{5}\) | |
| 6y - 3\(\frac{1}{2}\) |
