Question

The sum of the two digits is 15 and the difference between them is 3. What is the product of the digits

​

Answer 1

Answer:

Step-by-step explanation: Let the two no's be x and y

therefore the eqns on the above conditions are,

x+y=15.....(1) and take the larger no as x and smaller as y

Therefore, x-y=3....(2) and solve 1 and 2 by elimination method

that gives, x=9 and y=6

xy=9*6=54.

Answer 2

Answer:

Step-by-step explanation:

Let the no.s be x and y

Acc. To the given information

X+y =13-------eq 1

X-y=3---------eq 2

Adding both the equations we get

2x=16 ; i.e.x=8

Putting x=8 in eq we get y=5

Product of xy will be 8*5=40

Hope this helps!
