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