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 -9b + 8b = 9b + 2x + 4 for b in terms of x.
| -6x + 1\(\frac{1}{2}\) | |
| -\(\frac{9}{14}\)x + \(\frac{1}{7}\) | |
| \(\frac{1}{3}\)x - \(\frac{2}{9}\) | |
| -3x + 3 |
