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 3b - 8b = 5b + 7x + 2 for b in terms of x.
| 11x - 5 | |
| -7\(\frac{1}{2}\)x - 1 | |
| -2\(\frac{3}{4}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{6}{13}\)x + \(\frac{8}{13}\) |
