if 2x = -4, then what is the value of 8x?
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.
To find the value of 8x, we can first solve the given equation 2x = -4 for x.
Dividing both sides of the equation by 2, we have:
(2x)/2 = -4/2
x = -2
Now that we have the value of x, we can substitute it into the expression 8x:
8x = 8(-2)
8x = -16
Therefore, the value of 8x is -16.
To find the value of 8x, we need to first determine the value of x.
Given that 2x = -4, we can solve for x by dividing both sides of the equation by 2.
Dividing -4 by 2 yields -2, so x = -2.
Now that we know the value of x, we can substitute it into the expression 8x:
8 * (-2) = -16
Thus, the value of 8x is -16.
