Question

1) 4+8r-6r=6+2r 2) 1-3x=-6+7-2x-x

Answer 1

1:-

$\\ \sf \longmapsto 4+8r-6r=6+2r$

$\\ \sf \longmapsto 4+2r=6+2r$

$\\ \sf \longmapsto 2r-2r=6-4$

$\\ \sf \longmapsto 0=2$

$\\ \sf \longmapsto r=\infty$

2:-

$\\ \sf \longmapsto 1-3x=-6+7-2x-x$

$\\ \sf \longmapsto 1-3x=1-3x$

$\\ \sf \longmapsto 0=0$

$\\ \sf \longmapsto x=\infty$
