Answered by abhi569

Your question is incomplete :

According to the question,

3 of x - y + 20 = 200

=> 3x - y + 20 = 200

=> 3x - y = 180

$.$

nikky12345: send the 3 to right side then that will be 180 by 3 cancel it then 60 answer. X - Y =60

abhi569: You are going wrong

3x - y + 20 = 200 .... equation1

y = 3x +20 + 200
y = 2x + 220 ......eq 2

putting this value of y in equation1

3x - 2x - 220 + 20 = 200
x = 200 + 200
x = 400

Putting the value of x in equ2

y = 2*400 + 220
y = 1020.

nikky12345: no wrong

842abhinavkumar: you need value of x and y Right?

842abhinavkumar: tell me whats wrong

842abhinavkumar: it was not mentioned in question what to do thats why i just found value of x and y

842abhinavkumar: and those values are 100% correct
