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 9a - 9a = 2a - 6y - 8 for a in terms of y.
| \(\frac{3}{7}\)y - 1\(\frac{1}{7}\) | |
| -\(\frac{1}{11}\)y + \(\frac{6}{11}\) | |
| 1\(\frac{2}{7}\)y + \(\frac{6}{7}\) | |
| y - 6 |
