Respuesta :

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

Answer:

see explanation

Step-by-step 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
