Question

a digit in the tens place of a two digit number is four more than two times the digit in the units place, if the digit in the units place is x and the number is 61 , the value of x will be _______​

Answer 1

Answer:

x=1 and y=6

Step-by-step explanation:

Let the number be 10y+x=61

ATQ - y+4=2x

y-2x=4

=> 10y+x=61 ------(1)

y -2x=4. ------(2)

Multiplying eq(1) by 2 and then adding both the equations

.

20y+2x=122

y-2x =4

21y=126

y=6

Putting the value of y in eq (2)

6-2x=4

6-4=2x

2=2x

x=1
