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 - 5b = -9b + 4z - 5 for b in terms of z.
| -\(\frac{2}{5}\)z + \(\frac{1}{10}\) | |
| -3\(\frac{2}{3}\)z + 1\(\frac{2}{3}\) | |
| \(\frac{3}{4}\)z - \(\frac{5}{12}\) | |
| -3z - \(\frac{1}{2}\) |
