Question 1084597

{{{abs(2x+1)+1<=8}}}

{{{abs(2x+1)<=8-1}}}...recall that {{{abs(2x+1)=sqrt(2x+1)}}}; so, you have {{{2x+1}}} and {{{-(2x+1)}}}

then,

{{{2x+1<=7}}}

{{{2x<=7-1}}}

{{{2x<=6}}}

{{{x<=6/2}}}

{{{x<=3}}}

or

{{{-(2x+1)<=7}}}

{{{-2x-1<=7}}}

{{{-7-1<=2x}}}

{{{-8<=2x}}}

{{{-8/2<=x}}}

{{{-4<=x}}}



solution:

{{{-4<=x<3}}}
