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 - 3b = 2b - 2z - 6 for b in terms of z.
| -2\(\frac{1}{2}\)z - \(\frac{1}{4}\) | |
| z - 6 | |
| 4z - 8 | |
| 1\(\frac{2}{7}\)z + \(\frac{1}{7}\) |
