To find the value of 8x when 2x equals -4, we first need to solve the equation 2x = -4.
To do this, we divide both sides of the equation by 2:
2x/2 = -4/2
x = -2
Now that we know x equals -2, we can substitute this value into the expression 8x:
8x = 8(-2)
8x = -16
Therefore, when 2x equals -4, 8x equals -16.
