Question 3 of 5
Two Variables

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 - 7b = -2b - 6z - 6 for b in terms of z.

\(\frac{1}{8}\)z - \(\frac{3}{4}\)
z - 6
\(\frac{1}{3}\)z + \(\frac{2}{5}\)
-2\(\frac{1}{5}\)z + \(\frac{4}{5}\)
