I solve this question with myself not paste from internet so mark me as brainlist.
Let the 2 digit number containing digit be x ( on tens place ) and y ( on ones place ).
then, number be 10x + y
According to question :-
8 ( x + y ) - 5 = 10x + y
8x + 8y - 5 = 10x + y
8x - 10x + 8y - y = 5
-2x + 7y = 5 ( . . . i)
OR
16 ( x - y ) + 3 = 10x + y
16x - 16y + 3 = 10x + y
16x - 10x - 16y - y = -3
6x - 17y = -3 ( . . . ii)
Now, subtract (i) term from (ii) term
for subtracting first multiply 1st term with -3 for removing the x term :-
-3 (-2x + 7y = 5)
6x - 21y = -15
then, (. . . ii) - ( . . . i)
6x - 17y = -3
- 6x - 21y = -15
- + = +
4y = 12
then, y = 12/4 = 3
Let take (i) term to putting the value of y for finding the value of x :-
-2x + 7y = 5
-2x + (7×3) = 5
-2x + 21 = 5
21 - 5 = 2x
16 = 2x
16/2 = x
8 = x
Hence, the number is
=> 10x + y = (10×8) + 3 = 80 + 3 = 83
I hope it's help you please mark me as Brainlist.
