Question

frame the línear equation in 2 variable. a two digit no. is 3 more than 4 times the sums of it's digit​

Answer 1

Answer:

Let the tens and unit digit of number are  x,y

First condition :

⇒10x+y=3+4(x+y)

⇒6x−3y=3

⇒2x−y=1

Second condition :

⇒10x+y+18=10y+x

⇒x−y=−2

Subtract resultant equations ;

⇒x=3

⇒y=5

∴two digit number =35

Answer 2

Answer:

2x-1-y=0

Step-by-step explanation:

digits=x,y

no. = 10x+y

given, (10x+y)-4(x+y)=3

10x+y-4x-4y-3=0

6x-3y-3=0

3(2x-y-1) =0

2x-y-1=0
