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 + 2b = 8b - 4z + 3 for b in terms of z.
| -1\(\frac{1}{7}\)z + \(\frac{4}{7}\) | |
| \(\frac{6}{17}\)z - \(\frac{3}{17}\) | |
| 1\(\frac{2}{5}\)z + \(\frac{2}{5}\) | |
| -12z - 1 |
