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 2b - 2b = 6b - 8z - 2 for b in terms of z.
| 13z - 7 | |
| 1\(\frac{1}{2}\)z + \(\frac{1}{2}\) | |
| z - 1 | |
| \(\frac{1}{8}\)z - \(\frac{1}{2}\) |
