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