Answer:
x=6,y= 7
Step-by-step explanation:
-6x +7y= 13
-6x+8y=20
-y = -7
divide through by -1
y =7
sub y= 7 in equation 1
then x= 6
Did you mean
81* 9∧(-2b-2)=27 => First divide whole equation with 81 and get
(3∧2)∧(-2b-2)=1/3 => 3∧(-4b-4)=3∧(-1) => -4b-4=-1 => -4b= -1+4 => -4b=3 =>
we will multiply whole equation with (-1) and get 4b=-3 => b=-(3/4)
If the start item is correct.
Good luck!!!
I believe it would just be b=1m or b=m. the reason i added the 1 in front of the m was to show you that the books would equal 1 per month. b and m are equal to each other because the rate is 1 book per 1 month.
