The sum of 2 numbers is 1855. their difference is 259. what are they? plz answer

If you would like to know the values of these numbers, you can calculate this using the following steps:

a + b = 1855
a - b = 259 ... a = 259 + b

a + b = 1855
(259 + b) + b = 1855
259 + 2 * b = 1855
2 * b = 1855 - 259
2 * b = 1596    /2
b = 1596 / 2
b = 798

a = 259 + b = 259 + 798 = 1057

Result: The numbers are 798 and 1057.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
