Question

Everyone please I beg you! I need serious help on this! How do explain this has no solutions-

Answer 1

see explanation

Explanation:

Given

x + 3 = x - 15 ( subtract 3 from both sides )

x = x - 18 ( subtract x from both sides )

0 = - 18 ← not possible

This indicates the equation has no solution

Answer 2

I've done something very similar to this recently, and I think that it's no solutions because once simplified, the 2 sides don't equal eachother, but I'm not entirely sure how it would work for the other solution types
