Question

X is a two digit number and sum of the digit of x is 7

Answer 1

Answer:

43 is the correct answer because when we add 4+3 then it equal to 7

Answer 2

Answer:

x=48/9

Step-by-step explanation:

let the two no. be x and y

their sum is 6 therefore, the no. is

= x+y=6

let the x be in 10's place and y in one's place

=10x+y

the new no. after enterchanging

=10y+x

According to question the new no. is 2 greater than the original no.then,

10x+y-2=10y+x

10x-x-2=10y-y

9x-2=9y

9x-9y=2

9(x-y)=2

x-y=2/9

ATQ

 x+y=6

+x-y=2/9

2x=2/9+6

2x=2/9+54/9

x=56/9*2

x=48/9
