Answer: Let the 2 numbers be x and

sum of two numbers is 28....Eq 1: x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2: 6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

hope it helped
