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 -2a - 9a = 8a - 5y - 6 for a in terms of y.
| -\(\frac{2}{5}\)y + \(\frac{3}{5}\) | |
| \(\frac{2}{7}\)y + \(\frac{3}{14}\) | |
| -5y - 3 | |
| 3y + 4 |
