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 2b - 4b = b + 8x + 8 for b in terms of x.
| \(\frac{3}{4}\)x + \(\frac{5}{16}\) | |
| -1\(\frac{2}{3}\)x - \(\frac{7}{9}\) | |
| 1\(\frac{1}{8}\)x - \(\frac{7}{8}\) | |
| 12x + 8 |
