<span>3a+4x=29 (1st)
2a-3x=-9 (2nd)
multiply (1st) by 3 and (2nd) by 4
</span>9a + 12x = 87 (1st)
8a - 12x = -36 (2nd)
---------------------add
17a = 51
a = 3
<span>2a-3x=-9
</span><span>2(3)-3x=-9
6 - 3x = -9
-3x = -15
x = 5
answer
x = 5 and a = 3</span>
The total number of barrels on each trip=96
amount of quarts per barrel=30
The total amount of barrels picked on each trip will be:
96*30=2,880 quarts
The number of days required to pickup the barrels will be:
[total number of barrels]/[rate]
2880/13
=221.54 hours
but
1 day=24 hours
thus;
221.54 hrs=221.54/24 days=9.23 days
