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