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 4b - 2b = 9b - 2x + 5 for b in terms of x.
| x - 1 | |
| 1\(\frac{1}{4}\)x - \(\frac{3}{8}\) | |
| \(\frac{7}{11}\)x + \(\frac{3}{11}\) | |
| 7x - 1 |
