Did you even think that out?

Yes, it is a basic rule in algebra that any nonzero number or algebraic expression divided by itself equals 1, provided that it is defined. So, -7x divided by -7x equals 1, as long as x is not zero.

If 2x=−4 , then what is the value of 8x ?
Explain what the question is trying to ask.
9 months ago
The question is trying to find the value of 8x, given that 2x equals -4.
From "2x = -4," we can find the value of x by dividing both sides by 2, which gives us "x = -2." Once we know that each x is -2, we can find out what 8x is by multiplying 8 times -2.
So the question is essentially trying to use the given equation to solve for a related question about the same variable.

so the answer is?

The answer is -16.
If x = -2 (from the equation 2x = -4), then 8x = 8 * -2 = -16.

To simplify the expression -7x divided by -7x, we can cancel out the common factors. In this case, the common factor is -7x.
Dividing -7x by -7x is the same as multiplying it by the reciprocal of -7x, which is 1/(-7x) or -1/(7x). Therefore, the simplified expression is -1/(7x) or -1/7x.
