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 9b - 5b = -b + 9z - 6 for b in terms of z.
| z - 2\(\frac{1}{3}\) | |
| 1\(\frac{2}{5}\)z - \(\frac{3}{5}\) | |
| 7z + 4 | |
| 3\(\frac{1}{2}\)z + 1\(\frac{1}{2}\) |
