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 = b + 7z - 4 for b in terms of z.
| 1\(\frac{3}{4}\)z + \(\frac{3}{4}\) | |
| \(\frac{14}{15}\)z + \(\frac{2}{15}\) | |
| 1\(\frac{1}{15}\)z - \(\frac{4}{15}\) | |
| 5z - 2 |
