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