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 8b - b = -5b - 4x + 9 for b in terms of x.
| -\(\frac{3}{13}\)x + \(\frac{9}{13}\) | |
| x - 1\(\frac{1}{2}\) | |
| x - 6 | |
| -1\(\frac{3}{13}\)x + \(\frac{7}{13}\) |
