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 2b - 7b = b - 4y + 5 for b in terms of y.
| -2\(\frac{2}{5}\)y + \(\frac{3}{5}\) | |
| 3y + 5 | |
| -\(\frac{1}{13}\)y + \(\frac{4}{13}\) | |
| -3\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) |
