Let us call each number x and y.
Ok, x+ y= 30
And difference is 6.
Assuming no difference between variables, x = 18 and y= 12. These total 30.
And 18 - 12 = 6, which satisfies the second part of the question.
Simple way to check:
You know x+y = 30.you know difference is six.
So, divide 30 by 2 . That gives you 15 for x, 15 for y.
Now, you have difference of six, divide by two, that equals 3.
NOw, add 3 to 15 (say for x) that's 18.
NOw, minus 3 from 15 (for y), that's 12.
