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