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 - 2b = -b + 8z - 3 for b in terms of z.
| 1\(\frac{1}{9}\)z - \(\frac{1}{3}\) | |
| -\(\frac{1}{8}\)z - \(\frac{1}{16}\) | |
| -2z - 1 | |
| \(\frac{4}{9}\)z - \(\frac{1}{6}\) |
