If 2x= −4 , then what is the value of 8x ?

Answer 1

To find the value of 8x, we need to determine the value of x.

Given that 2x = -4, we can solve for x by dividing both sides of the equation by 2:

2x/2 = -4/2

x = -2

Now that we know the value of x is -2, we can substitute it into the expression 8x:

8(-2) = -16

Therefore, the value of 8x is -16.
