Name both equation X+3y=7-----eq 1 2x+y=5------eq 2 From 2: find value of y=5-2x-----eq 3 Put y in eq 1: We get: x+3(5-2x)=7 x+15-6x=7 x-6x=7-15 -5x=-8 x=8\5 NOW put put x in any one of the above equations such as we consider ep 2: 2(8/5)+y=5 16/5 +y=5 y=5-16/5. :taking LCM y=25-16/5 y=9/5 Now for the given condition x/y Simply putting values of x and y We get: 8/5|9/5 8/5 *5/9. Both 5 cancelled Then the answer is 8/9.

Sir plz make a full video on fast Entry test preparation ❤
Sir logical reasoning py aik video plz
Sir nts Mai Jo logical reasoning hoti hai us ka to kuch batai
Sir ratio and proportion par bhi video banaye
sir Q12 main agar 2 ko base bana k powers add karin 1 answer a raha hy.
This type of Power rule Only valid for multiplocation
Sir first we multiple 2 on eq 1 and than we add them it gives x=7/5 and y=14/5 and we divide them x/y=2 is answer sir its wrong or ture 🤔
Yes sir that answer is wrong I made a mistake in the above step thank for reaction 😊😊
Anyone plz Tell me how to solve Q:15
Name both equation
X+3y=7-----eq 1
2x+y=5------eq 2
From 2: find value of
y=5-2x-----eq 3
Put y in eq 1:
We get:
x+3(5-2x)=7
x+15-6x=7
x-6x=7-15
-5x=-8
x=8\5
NOW put put x in any one of the above equations such as we consider ep 2:
2(8/5)+y=5
16/5 +y=5
y=5-16/5. :taking LCM
y=25-16/5
y=9/5
Now for the given condition x/y
Simply putting values of x and y
We get:
8/5|9/5
8/5 *5/9. Both 5 cancelled
Then the answer is 8/9.
