Question 832791
5x+3>4x+7
     
SUBTRACT 4X ON BOTH SIDES TO GET THE VARIABLE ON ONE SIDE

  5x+3>4x+7
 -4x      -4x
_________________
x+3>7

SUBTRACT 3 ON BOTH SIDES TO HAVE THE NUMBERS ON ONE SIDE

x+3>7
    -3 -3
__________
x>4 

If you plug in 4 for x you get both sides equaling 23. This proves that x must be greater than 4. (You can treat the inequality sign like an equal sign.)

I hope this helped you.
