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 -b - 5b = 9b - 4z - 5 for b in terms of z.
| -\(\frac{1}{10}\)z + \(\frac{1}{2}\) | |
| -1\(\frac{2}{5}\)z - 1 | |
| \(\frac{13}{14}\)z + \(\frac{1}{7}\) | |
| -1\(\frac{1}{3}\)z - 1\(\frac{1}{2}\) |
