Answer 1
Answer: 40 - x < 3x

Simplify both sides of inequality:

−x + 40 < 3x
Subtract 3x on both sides:

−x + 40 − 3x < 3x − 3x−4x + 40 < 0

Divide both sides by -4:

-4x/-4 < -40/-4

x > 10

C. x > 10
Answer 2
Answer: Solutions for  40 - x < 3x

To find the answer we have to solve the equation 40 - x < 3x. 

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

1) The first step is to add x to each side 
40 < 3x+x

2) Next you simplify 3x+x. To simplify 3x+x you add the x to 3. 3x+x = 4x  
40 < 4x

3) Divide both of the sides by 4
(40)/(4) < x

4) Simplify the fraction (40)/(4) to 10. You simplify it to ten because 40 ÷ 4 = 10.
10<x

5) Answer 
x= > 10

The correct choice is C.
