Question 1141632
<pre>{{{matrix(1,3, abs(2x-2), ""<"", 14) }}}

means

{{{matrix(1,5,-14,""<"",2x-2,""<"",14)}}}

Solve for x in the middle.  Add +2 to all three sides:

{{{matrix(1,5,-14+2,""<"",2x-2+2,""<"",14+2)}}}

{{{matrix(1,5,-12,""<"",2x,""<"",16)}}}

Divide all three sides by 2

{{{matrix(1,5,-6,""<"",x,""<"",8)}}}

Set builder notation

{{{matrix(1,9,

"{",x,"|",-6,""<"",x,""<"",8,"}")}}}

Interval notation:

{{{(matrix(1,3,-6,",",8))}}}
