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