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 -5b + 2b = -8b + 9z - 2 for b in terms of z.

-\(\frac{4}{9}\)z - \(\frac{7}{9}\)
1\(\frac{7}{9}\)z - 1
2\(\frac{1}{3}\)z - \(\frac{2}{3}\)
1\(\frac{1}{6}\)z - \(\frac{1}{2}\)
