Answer:
If x÷4 = 4÷x,what is the value of x?
x ÷ 4 = 4 ÷ x
x/4 = 4/x
Cross-multiplying, we get:
x(x) = 4(4)
x² = 16
We now see that we actually have a quadratic equation; therefore, there will be TWO desired values of x, not just one.
Now, take the square root of both sides:
√(x²) = ±√(16)
x = ±4
CHECK:
x/4 = 4/x
4/4 = 4/4
1 = 1
x/4 = 4/x
-4/4 = 4/-4
-1 = -1
Therefore, the TWO values of x which make the given equation true are:
4 and -4.

hello hope helps you.
will u be my friend?
Answer:
[tex]4x \times 4 = 0[/tex]
=> 4x = 0÷4
=> 4x = 0
=> x= 0÷4
Hence the value of x is 0
