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 + 9a = a + 8y + 6 for a in terms of y.
| -\(\frac{1}{7}\)y + \(\frac{6}{7}\) | |
| \(\frac{3}{5}\)y + \(\frac{4}{5}\) | |
| 1\(\frac{1}{2}\)y + 3\(\frac{1}{2}\) | |
| \(\frac{1}{16}\)y - \(\frac{1}{8}\) |
