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