let the larger of two numbers be x and the smaller y
five time the larger of two numbers plus four times the smaller is+271:
5x%2B4y=271.....eq.1
if three times the larger less twice the smaller is 261, then
3x-2y=261.....eq.2
solve the system:
5x%2B4y=271.....eq.1
3x-2y=261.....eq.2.....both sides multiply by 2
---------------------
5x%2B4y=271.....eq.1
6x-4y=522.....eq.2
---------------------------add both eq.1 and eq.2
5x%2B4y%2B6x-4y=271%2B522
5x%2Bcross%284y%29%2B6x-cross%284y%29=793
11x=793
x=793%2F11
x=72.09090909090909
x=72.09
go to 3x-2y=261.....eq.2 substitute x
3%2A72.09-2y=261
216.27-261=2y
-44.73=2y
y=-44.73%2F2
y=-22.37
