system of linear equations

Let the smaller number be x....then the larger number is  2x + 10....so we have

[x] +  [2x + 10]  = 97    simplify

3x + 10  = 97      subtract 10 from both sides

3x = 87        divide both sides by 3

x = 29    and this is the smaller number

And   2(29) + 10  =  68  is the larger number

Let the smaller number be x

Then the larger number is:(2x) +10, so we have

x +2x +10=97

3x=97-10=87 Divide both sides by 3 and we have

x=87/3=29 This is the smaller number.

(29*2) + 10=68 This is the larger number, so that:

29 + 68=97, which is your answer.
