Answer 2

Answer:

Step-by-step explanation:

Since it has to be done by trial and error method. Put different values of x to match rhs to LHS.

We see that smaller numbers like 1,3,5 will not fit the equation

2x-12 =15

or 2x - 12- 15 = 0

or 2x -27 =0

So let's put x=13.5

2×13.5 - 27= 0

so 0 = 0

LHS=Rhs
