Plz check the question again.

Answer 2

hello here is your answer by Sujeet yaduvanshi ☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝


By elimination method for solving the equation:----

51x+49y=150. *49
49x+51y=50*51

_____________

2499x+2401y=7350
2499x+2601y=2550

_________________
200y=4800
y=4800/200
y=-24


then,

51x+49y=150
51x+49*24=150
51x-1176=150
51x=150+1176
51x=1326
x=1326/51
x=26


then,


value of x-y
26-(-24)
26+24
50



Again,

value of x+y
26+(-24)
26-24

that's all
