Answer:

#x > 4#

Explanation:

#10x - 7 > 2x + 25#

Subtract #color(blue)(2x)# from both sides:
#10x - 7 quadcolor(blue)(-quad2x) > 2x + 25 quadcolor(blue)(-quad2x)#

#8x - 7 > 25#

Add #color(blue)7# to both sides:
#8x - 7 quadcolor(blue)(+quad7) > 25 quadcolor(blue)(+quad7)#

#8x > 32#

Divide both sides by #color(blue)8#:
#(8x)/color(blue)8 > 32/color(blue)8#

#x > 4#

This can be said as "#x# is greater than 4."

Hope this helps!
