Respuesta :

You would subtract 11 on both sides of the equation.
Then multiply the reciprocal of 1/2 which is 2.
And you should get -16 as your answer 
Subtract 1 from both sides of the equal sign. (3-11 and 11-11) So, now you only have -8 = 1/2b ... Next, divide 1/2 from both sides (because you need to make the variable, b, be the only thing on one side of the equal sign) and you get -4 = b . So, your answer is -4.
