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
2, because 2 can only be divided by 1 and itself, and thats what a prime number is
At x=-2
vertically opposite angles
