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 = b + 8z - 1 for b in terms of z.
| z - \(\frac{1}{5}\) | |
| \(\frac{1}{2}\)z - 1\(\frac{1}{4}\) | |
| -\(\frac{5}{12}\)z - \(\frac{7}{12}\) | |
| -1\(\frac{4}{9}\)z + \(\frac{1}{9}\) |
