Question

What is the value of x in the equation 4(2x 10) = 0? −5 −7 5 7

Answer 1

4(2x+10)= 0
8x+40=0
subtract 40 from both sides
8x+40-40=0-40
8x=-40
x=-40/8
x=-5



4(2x-10)=0
8x-40=0
Add 40 from both sides
8x-40+40=0+40
8x=40
x=40/8
x=5

Answer 2

Answer:

The correct option is 1. The value of x is -5.

Step-by-step explanation:

The given equation is

$4(2x+10)=0$

Divide both sides by 4.

$2x+10=0$

Subtract 10 from both the sides.

$2x+10-10=-10$

$2x=-10$

Divide both sides by 2.

$x=-5$

The value of x is -5. Therefore option 1 is correct.
