Question 831420
Let x =smaller no.
       X+5= larger no.
thrice the larger; that is 3(x+5)
Twice another number = 2x

We make equation. If the sum of 2numbers is 50 then ,we write
3(x+5) + 2x = 50
3x+15 +2x = 50   solve for x
5x= 50-15
5x/5= 35/5
X= 7 is the smaller no.

solve for larger number by substituting;

X+5= 7+5= 12 is the large no.

Checking
Subs. To equation 3(x+5) + 2x =50
       3(7+5) + 2(7)= 50
       3(12) +14 =50
       36+14=50
              50 =50  true

The numbers are 7 and 12.
