Question

the sum of two numbers is 68 the large number is 18 more than the smaller number what are the numbers

Answer 1

Really simple. Divide by 2 then add and subtract 9
68/2 = 34
34 + 9 = 43
34 - 9 = 25
43 -  25 = 18
The two numbers are 43 and 25

Answer 2

Let x = the smaller number

Ley y = the larger number

y = x + 18 = 68

x + (x+20) = 68

2x + 18 = 68

2x = 50

x = 25

y = x + 18

y = 25 + 18

y = 43
