−11b+7=40
like what am i supposed to do? ?

The answer is 3

Step-by-step explanation:

First write the equation as you see it.

-11b+7=40

Then switch the take away seven from the left side then place it in the right side but as a minus.

-11b=40-7

Next do the math on the right side.

-11b=33

Once you have done that you divide the number on right with the number on the left which leaves you with the answer.

b=-3

Hope this helped :)
