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 - 5b = 4b - 7x + 9 for b in terms of x.
| \(\frac{7}{16}\)x + \(\frac{5}{16}\) | |
| \(\frac{2}{3}\)x + \(\frac{1}{6}\) | |
| \(\frac{2}{5}\)x - 1\(\frac{4}{5}\) | |
| 5x - 2 |
