Question

the sum of the two digit number is 12. the number is 6 times the unit digit​

Answer 1

Answer:

the number is 48

Step-by-step explanation:

x + y = 12 equ (1)

10x + y = 6y

10x - 5y = 0

2x - y = 0 equ (2)

solving equations (1) & (2)

3x = 12

x = 12/3

x = 4

substitute x in equation (1)

x + y = 12

4 + y = 12

y = 12 - 4

y = 8

the required number is 10x + y

= 10(4) + 8

= 40 + 8

= 48
