Answer» the TWO no.s are 8 and 5Step-by-step explanation:Explanation:CONSIDER the two NUMBERS as x and y . From the GIVEN data, we write:x−y=3 x+y=13 From the first equation, we determine a value for x .x−y=3 Add y to both sides.x=y+3 In the second equation, substitute x with (y+3) .x+y=13 (y+3)+y=13 OPEN the brackets and simplify.y+3+y=13 2y+3=13 Subtract 3 from each side.2y=10 Divide both sides by 2 .y=5In the first equation, substitute y with 5 .x−y=3 x−5=3 Add 5 to each side.x=8 |
