Question

prove that 1+2=4
and show that 1-2(2)=5​

Answer 1

Solution:

Let a=0

We Know that,

Anything multiplied to 0 then it equals to zero.

So, If a=0

Then 3a=0 (3×0=0).........I

4a=0 (3×0=0).........II

5a=0 (3×0=0).........III

Here I and II ,

3a=0=4a

3a=4a

3=4

*1+2=4*

Here I and III ,

3a=0=5a

3a=5a

3=5

1-4=5

*1-2(2)=5*
