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 5b - 4b = 9b + 6x - 5 for b in terms of x.
| -3x - 4 | |
| -\(\frac{2}{9}\)x + \(\frac{2}{3}\) | |
| -2\(\frac{1}{2}\)x + 1\(\frac{1}{4}\) | |
| -2x + 3 |
