Question

Can 2x and x+2 have the same value? What is x? How do you know that is the only number x can be?

Answer 1

Yes, x=2, there can be no other number.

Explanation:

Putting these two terms equal, we get 2x = x + 2. Subtracting x from both sides, we are left with x = 2. Since this equation says x is equal to two, there can be no other values of x. It cannot be a positive number, and if it was negative, it would never work, since multiplying a negative by two makes it smaller, and adding by 2 makes it bigger.

Answer 2

2x = x + 2

2x - x = 2

x = 2

2 × 2 = 2 + 2

4 = 4

I hope that helps !!
