Solution :
[c] The given equations are |
\[x-y=2\] ...(1) |
\[x+y=4\] ...(2) |
On adding eqs, (1) and (2), we get |
\[2x=6\,\,\,\,\,\,\,\,\,\,\,\,\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,x=3\] ...(3) |
\[\therefore \,\,\,\,\,\,\,\,\,\,\,\,y=1\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\Rightarrow \,\,\,\,\,\,\,\,a=3,\,b=1\] |
