Respuesta :

-15 = 11 - 2 * 13

hope this helps : /

Answer:

b= 13

Step-by-step explanation:

First, to make it easier, I switch the order of the equation(it does not change the answer depending on how you change it) to -2b+11= -15. It is the same thing as -15 =11-2b, just the order is switched to make it seem simpler. Now, we subtract 11 from both sides(-15-11) to get -2b= -26. After that, you divide -2b  from -26, which is 13
