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