Answer:

x > 3

Explanation:

You have the following inequality:


-4(2x-7)<10-2x

In order to obtain the solution for x, you first apply distribution property in the left term of the inequality:


-4(2x)-4(-7)<10-2x\\\\-8x+28<10-2x

Next, you sum 2x on both sides, and you subtract 28 on both sides too:


-8x+2x+28-28<10-28-2x+2x\\\\-6x<-18

(where you have simplifies similar terms)

Finally, you divide the inequality for -6, but you take into account that the inequality symbol change (because the operation with a negative term):


(-6x)/(-6)<(-18)/(-6)\\\\x>3

hence, the solution to the inequality is x > 3
