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