well, you can do anything to it as long as you it to both sides
(also if you divide or multply by a negaive, you have to flip the sign like from > to < and vice verca)
7x>56
we want only 1x
7/7=1 so
divide both sides by 7 to keep it same
7/7x>56/7
1x>8
x>8
x is greater than 8 but not including 8 is teh solution
x>8
