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 = 4b + 6x - 7 for b in terms of x.
| -5x + 2\(\frac{1}{3}\) | |
| 7x - 7 | |
| 2\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| \(\frac{2}{11}\)x - \(\frac{9}{11}\) |
