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
8x = -40
x = -5

Answer 2

Answer:

-5

Step-by-step explanation:

To Solve x we can use the product rule and multiply 4 in the the brackets:

$4*(2*x+10)=0$

$8*x+40=0$

We can move the fourty to the right hand side of the equal sign and then simplify the equation by dividing the whole expression by 8:

$8*x=-40$

$x=-40/8=-5$

The value of x is -5
