Answer 2

Answer:

Original number 10x + y= 5 ---- (1)

Reversed number 10y + x= 14-----(2)

Multiply 1 and 2 by ten

100y + 10x = 140

10y + 100x = 50 (subtract)

90y - 90x = 90

÷ 90 u get y- x = 1

100y + 10x= 140

10y + 100x = 50 ( add)

110y + 110x = 190

÷ 110 u get

y + x = 1.72

y+x= 1.72

y-x= 1

2y = 2.72

y = . 72 and x = 1
