In a normal mathematical language this assignment sounds this way:

    Solve inequality 3(x+8) < 7x.

To solve it, first simplify

3x + 24 < 7x.


Then subtract 3x from borh sides. You will get

24 < 7x - 3x,   or  4x > 24.


Divide by 4 both sides. You will get

x >  = 6.


So, inequality  x > 6 is your solution.


For example,  x= 7  is the value  for which  3*(7+8) = 3*15 = 45   is less than 7*7 = 49, and your original inequality is satisfied.

Solved.
