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 + 9b = b + 9x - 2 for b in terms of x.
| 3\(\frac{1}{3}\)x + 1\(\frac{2}{3}\) | |
| x + 1 | |
| 1\(\frac{1}{3}\)x + 2\(\frac{2}{3}\) | |
| -x + \(\frac{9}{13}\) |
