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 -8a - 2a = 9a + 6y - 1 for a in terms of y.
| \(\frac{1}{3}\)y + \(\frac{1}{2}\) | |
| -\(\frac{8}{17}\)y + \(\frac{1}{17}\) | |
| \(\frac{1}{5}\)y + \(\frac{4}{5}\) | |
| -2\(\frac{1}{6}\)y - \(\frac{5}{6}\) |
