Question 4 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 8b + 8b = -4b + 7z - 9 for b in terms of z.

-\(\frac{1}{3}\)z - 2
-\(\frac{1}{12}\)z - \(\frac{3}{4}\)
-\(\frac{1}{8}\)z + \(\frac{1}{4}\)
-\(\frac{1}{2}\)z - \(\frac{1}{3}\)
