8-(b-2)=11 show work please so I can learn how to do it and thank you for answering
8-(b-2)=11
First you need to isolate the variable (in this case, b)
-(b-2)=3
Subtract 8 from each side to get rid of the 8
-b+2=3
Distribute the negative into the (b-2) .(negative is an understood -1)
-b=1
Subtract the 2 from each side to isolate the b
b=-1
Divide each side by -1 to get rid of the - on the b. (once again, - is an understood -1)
8-(-1-2)=11
8-(-3)=11
8+3=11
Now go back and plug -1 in for b to check your answer.
Theres probably another way to solve, but this is the easiest.
