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 + 4b = 3b + 6x + 5 for b in terms of x.
| \(\frac{1}{5}\)x + \(\frac{4}{15}\) | |
| -\(\frac{3}{10}\)x + \(\frac{2}{5}\) | |
| x + 2\(\frac{1}{2}\) | |
| 6x + 9 |
