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 6b - 3b = 2b + 9z + 8 for b in terms of z.
| \(\frac{2}{17}\)z + \(\frac{2}{17}\) | |
| 3z + 2 | |
| \(\frac{3}{8}\)z - \(\frac{3}{4}\) | |
| -3z + \(\frac{2}{5}\) |
