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