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 -2b + 5b = 8b - 3x - 4 for b in terms of x.
| \(\frac{4}{5}\)x + \(\frac{2}{5}\) | |
| -\(\frac{3}{4}\)x - \(\frac{1}{2}\) | |
| 15x - 9 | |
| 2x + 3\(\frac{1}{2}\) |
