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 -3b + 9b = 5b + 5x + 9 for b in terms of x.
| \(\frac{1}{2}\)x - 1\(\frac{1}{8}\) | |
| \(\frac{7}{10}\)x - \(\frac{4}{5}\) | |
| -11x - 4 | |
| -\(\frac{1}{15}\)x + \(\frac{1}{3}\) |
