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 - b = -5b + 5z - 9 for b in terms of z.
| 2z + 1\(\frac{3}{5}\) | |
| z + 1\(\frac{2}{7}\) | |
| \(\frac{3}{4}\)z - 1\(\frac{1}{8}\) | |
| 3z - 1\(\frac{1}{2}\) |
