Question

the sum of two numbers x and y is is 800. if we subtract 120 from x and add 220 to y then the result of the subtraction is half the result of the addition

Answer 1

280 Or 620

Step-by-step explanation:

if you talk about that that is 800 and half of 800 is 400 and thus subtract

400-120=280 and when we add to 400+220=620 so there half difference is created .
