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