Question 2 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 2b + 4b = -7b - 2x + 8 for b in terms of x.

\(\frac{1}{4}\)x - \(\frac{1}{2}\)
-\(\frac{2}{3}\)x + \(\frac{8}{9}\)
-\(\frac{1}{2}\)x - \(\frac{1}{2}\)
-\(\frac{1}{6}\)x - 1
