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 -a - 2a = 9a - 6y + 1 for a in terms of y.
| \(\frac{2}{5}\)y - \(\frac{1}{10}\) | |
| 1\(\frac{2}{3}\)y + \(\frac{1}{2}\) | |
| \(\frac{7}{8}\)y - 1 | |
| 3y + 4 |
