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 -2b - 7b = -7b + 6z - 8 for b in terms of z.
| 3z - 6 | |
| \(\frac{3}{11}\)z - \(\frac{7}{11}\) | |
| 2\(\frac{3}{5}\)z - 1\(\frac{3}{5}\) | |
| -\(\frac{3}{10}\)z + \(\frac{4}{5}\) |
