Answer:x=1/108 is your answer
-5/6x-1/9x=-102
1/x(-5/6-1/9)=-102
1/x=-102/(-17/18)=-102×-18/17=108
x=1/108
7 out of 10 were carrying a backpack...and 3 out of 10 were not
that means 7/10 of the total students had backpacks and 3/10 of the total students did not
7/10 * 700 = 4900/10 = 490 had backpacks <==
3/10 * 700 = 2100/10 = 210 did not
Answer:
(2,3)
Step-by-step explanation:
The given system is
y=3x-3
y=2x-1
We equate both equations and solve for x.

Group like terms to get:


We put x=2 into y=3x-3 to get:

As an ordered pair the solution is (2,3)
