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 5b + 8b = 8b + 4x + 9 for b in terms of x.
| 1\(\frac{1}{2}\)x - \(\frac{2}{3}\) | |
| 1\(\frac{1}{3}\)x - 3 | |
| 6x + 5 | |
| 3\(\frac{1}{3}\)x + \(\frac{2}{3}\) |
