#x > 5#

Explanation:

We will solve the equation similar to a standard linear equation. We will need to make #x# the subject so...

#2x + 7 > 17#

subtract #7# from both sides leaving the greater than sign the same way.

#2x > 10#

Divide both sides by #2#, since the #2# is positive you do not change the sign, however if you divide by a negative you must change the sign around. So in this case leave the greater than sign.

#x > 5#
