Let two base numbers that is any of the digit from [0-9] be x and y.
It is given that, the product of the two base numbers is exactly twice as large as the sum of those same base numbers.
→xy=2×(x+y)
There are two variables in the equation , and there is only one equation.So, we have to use Hit and Trial method to evaluate the value of x and y.
→ 0≤ x≤9 and 0≤ y≤9
⇒ Integral Solution of the above equation can be evaluated by drawing the graph (Drawn the graph using Desmos)
1.⇒ x=4 and , y=4.
2.⇒ x=6 and y=3
3.⇒x=3 and y=6
4.⇒x=0 and y=0
