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