નીચેના વિધાનો સત્ય છે કે અસત્ય ? તમારા જવાબ માટે કારણ આપો :

કોષ્ટકમાં બિંદુઓના યામ આપેલાં છે : 

$\begin{array}{|c|c|c|c|c|c|} \hline x & 0 & 1 & 2 & 3 & 4 \\ \hline y & 2 & 3 & 4 & -5 & 6 \\ \hline \end{array}$

સમીકરણ $x - y + 2 = 0$ ના કેટલાક ઉકેલો છે.

Option A
Option B
Option C
Option D

Solution

The points $(0,2),(1,3),(2,4)$ and $(4,6)$ satisfy the given equation $x-y+2=0 .$ Each of these points is the solution of the equation $x-y+2=0 .$ But, the satisfy the given equation as $3-(-5)+2=0,$ i.e., $3+5+2=0$ or $10=0,$ which is false.

Hence, the given statement is false, since the point $(3,-5)$ does not satisfy the given equation.
