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 9b + 5b = b + 6y + 5 for b in terms of y.
| \(\frac{1}{8}\)y + \(\frac{5}{8}\) | |
| \(\frac{1}{4}\)y + 1\(\frac{1}{2}\) | |
| \(\frac{2}{5}\)y + \(\frac{9}{10}\) | |
| 2\(\frac{3}{4}\)y - \(\frac{1}{2}\) |
