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 - 8a = 9a - 6y - 8 for a in terms of y.
| -\(\frac{2}{11}\)y + \(\frac{8}{11}\) | |
| 5y + 3 | |
| -3\(\frac{1}{4}\)y + 2 | |
| 14y + 5 |
