Question

can someone tell me if my answer is correct?

Answer 1

How many solutions can be found for the equation 4x = 4x?

Zero
One
Two
Infinitely many

Answer 2

at first i chose One, it was wrong now i think it is Zero.

Answer 3

I think it's infinite. Since x can be anything for 4x = 4x to be true.

Answer 4

are u sure?

Answer 5

I think so.

Answer 6

Try three different numbers for x.
If all three work, then the answer must be infinite.

Let x = 1:
4(1) = 4(1)
4 = 4
x = 1 works

Now do the same for two other values of x.

Answer 7

x=7 4(7) = 4(7) oohhh. yeah its infinite then.

Answer 8

Think of 4x = 4x means.
x is a variable that stands for an number.
In this case the left side is 4 times a number.
The right side is exactly the same, 4 times the same number.
Since the same variable x is used on both sides, the variable represents the same number.
For every number, 4 times the number is always equal to 4 times the same number, so this equation is true for all numbers.
