The line under the less than sign means "possibly equal."

 

Therefore, the comparison is between:  2x  <= 10  which means "twice x is either less than or equal to 10"  and  2x  <  10 which means that "twice x is strictly less than 10 (and never equal to 10)."

 

Since x = 5, 2x = 10 which makes the first inequality true and makes the second inequality false.

if

\(x=5\)

then

\(2x=10\)

the\(\le\) sign means that it is less than or equal to.

the\(<\) sign means that it is strictly less than.

since we know that \(2x=10\), so we can have \(2x\le10\) but not \(2x<10\).
