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 b + 8b = -9b - 3y + 4 for b in terms of y.
| -1\(\frac{3}{4}\)y - \(\frac{3}{8}\) | |
| -\(\frac{1}{3}\)y + \(\frac{5}{12}\) | |
| \(\frac{3}{8}\)y - \(\frac{1}{2}\) | |
| -1\(\frac{1}{10}\)y + \(\frac{2}{5}\) |
