Question

Is 3+x=x+3 infinite,one solution, or no solution​

Answer 1

Infinite solutions

Explanation:

If we subtract 3 from both sides we get:

x = x

If we subtract x from both sides of that, we get:

0 = 0.

Well... 0 is ALWAYS equal to 0, so there is no answer that can make that statement invalid, meaning that all numbers are solutions.
