Respuesta :
no, you can’t subtract 3x from 6, since they are not like terms. You can think of it as the 6 does not have an x term, but in 3x, there is an x term.
Let's check that,
2(6- 3x) + x
= 12 -6x + x
= 12 -5x
But,
2(3) + x
= 6 + x
as we can see the results are different hence they are not equal.
