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 + 9b = 3b + 3y - 5 for b in terms of y.
| 1\(\frac{1}{6}\)y - \(\frac{1}{6}\) | |
| -\(\frac{3}{10}\)y + \(\frac{7}{10}\) | |
| -y - \(\frac{5}{6}\) | |
| -4y - 1\(\frac{2}{3}\) |
