Help me please. Will name brainliest.

Answer:
A
Step-by-step explanation:
If you simplify you get -45=75 and that’s not true.
Answer:
A 15x -45 = 15x+75
Step-by-step explanation:
When there is no solution the x coefficients are the same but the constants are different
15x -45 = 15x+75
Subtract 15x from each side
15x-15x -45 = 15x-15x+75
-45 = 75
This is never true so there is no value of x that can be put into the equation that will make this true
