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 + = -9b + y - 4 for b in terms of y.
| y + 2\(\frac{1}{4}\) | |
| -\(\frac{3}{8}\)y - \(\frac{3}{8}\) | |
| \(\frac{1}{8}\)y - \(\frac{1}{2}\) | |
| -\(\frac{7}{10}\)y - \(\frac{1}{5}\) |
