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 + 8b = -6b + x + 4 for b in terms of x.

-1\(\frac{2}{5}\)x + \(\frac{4}{5}\)
-x - 1\(\frac{1}{5}\)
-1\(\frac{4}{5}\)x + \(\frac{1}{5}\)
-\(\frac{1}{3}\)x + \(\frac{7}{12}\)
