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 - 9b = 4b + 3x + 7 for b in terms of x.
| -\(\frac{11}{12}\)x + \(\frac{1}{12}\) | |
| -\(\frac{7}{8}\)x + \(\frac{1}{2}\) | |
| 3x + 1\(\frac{3}{4}\) | |
| -1\(\frac{1}{5}\)x + 1\(\frac{1}{5}\) |
