Question

The sum of the digits of a two digit number is 7. If the digits are reversed, the new number decreased by 2 equals twice the original number. Frame the pair of equations using two variables

Answer 1

Answer:x = 2 and y = 5.

Step-by-step explanation:

Let x , y are numers of two digit number.

Given that sum of the two digit number = 7

So,

x + y = 7 ---------(1)

According to the question

10y + x – 2 = 2( 10x + y)

19x – 8y + 2 = 0 ----------------(2)

Here are your equations.
