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 + 9b = 3b - 4x - 9 for b in terms of x.
| \(\frac{1}{3}\)x - \(\frac{1}{6}\) | |
| \(\frac{3}{4}\)x - 1\(\frac{3}{4}\) | |
| 1\(\frac{1}{12}\)x + \(\frac{3}{4}\) | |
| -\(\frac{5}{6}\)x + \(\frac{5}{6}\) |
