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 - b = -6b + 7x + 8 for b in terms of x.
| 2x - 1\(\frac{1}{2}\) | |
| -2x - 3\(\frac{1}{2}\) | |
| \(\frac{4}{7}\)x + \(\frac{4}{7}\) | |
| x + \(\frac{2}{5}\) |
