Question

if 2x = -4, then what is the value of 8x?

Answer 1

To find the value of 8x, we need to solve the equation 2x = -4 for x first.

Dividing both sides of the equation by 2:

(2x)/2 = -4/2
x = -2

Now that we know x = -2, we can substitute this value into the equation 8x:

8x = 8(-2)
8x = -16

Therefore, the value of 8x is -16.
