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 - 3b = -9b - z - 4 for b in terms of z.
| -z + \(\frac{4}{5}\) | |
| \(\frac{1}{3}\)z - \(\frac{2}{3}\) | |
| -1\(\frac{7}{8}\)z - \(\frac{7}{8}\) | |
| -\(\frac{6}{11}\)z - \(\frac{4}{11}\) |
