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 = 3b - 2x + 7 for b in terms of x.
| -3\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| -x - 3 | |
| x - \(\frac{1}{3}\) | |
| 15x + 1 |
