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 -4b - 5b = -9b + 4z - 3 for b in terms of z.
| \(\frac{2}{3}\)z - \(\frac{1}{3}\) | |
| 13z + 4 | |
| -\(\frac{15}{17}\)z + \(\frac{2}{17}\) | |
| 1\(\frac{4}{5}\)z - \(\frac{3}{5}\) |
