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 -7b + 7b = 7b + x - 4 for b in terms of x.
| -\(\frac{3}{4}\)x + \(\frac{1}{8}\) | |
| \(\frac{3}{7}\)x + \(\frac{2}{7}\) | |
| -\(\frac{11}{12}\)x + \(\frac{1}{4}\) | |
| \(\frac{1}{2}\)x + \(\frac{9}{16}\) |
