Question 107771
1.
{{{x+2<4}}}...move {{{2}}} to the right

{{{x < 4-2}}}

{{{x < 2}}}}
here is the graph, and you need to draw dashed line because solution is every {{{x}}} from {{{-infinity}}} to {{{2}}}, excluding {{{2}}}.
({{{-infinity}}}, {{{2}}}]

2.


{{{x-y>1}}}


graph:
thisi is a function {{{x-1=y}}}, and you need to shade the area where {{{y<x-1}}}. 
That will be area from ({{{-infinity}}},{{{1}}}]
