Question 1002759
So the large number and the smaller number are both relative to the middle number. Let's find the middle number, let's call it x. The large number will be l and the small number s:
2x= l
x-5= s
-----------------
s+x+l= 43 Substitute in this equation with above values
x-5+x+2x= 43 Add 5 on both sides:
x+x+2x= 48
4x= 48
x= 12 This is the middle number. The small number is:
x-5= s
12-5= 7 is the small number. And the large number:
2x=l
2(12)= l
l= 24 This is your big number
-----------------
Proof:
7+12+24= 43 We have the correct answer
