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 = 8b - x - 5 for b in terms of x.
| 1\(\frac{3}{7}\)x + \(\frac{5}{7}\) | |
| -3x + 3\(\frac{1}{2}\) | |
| 1\(\frac{1}{6}\)x - 1 | |
| \(\frac{5}{8}\)x - \(\frac{5}{8}\) |
