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 -a - 9a = -9a - 4y + 6 for a in terms of y.
| \(\frac{5}{8}\)y + \(\frac{3}{4}\) | |
| \(\frac{7}{8}\)y - \(\frac{1}{4}\) | |
| y + \(\frac{1}{5}\) | |
| y + \(\frac{5}{18}\) |
