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 + 8b = -9b + 5x - 9 for b in terms of x.
| -\(\frac{3}{10}\)x - \(\frac{9}{10}\) | |
| -x - 1 | |
| \(\frac{1}{2}\)x + \(\frac{1}{3}\) | |
| -\(\frac{3}{14}\)x - \(\frac{3}{7}\) |
