Answer:
6x + 3
Step-by-step explanation:
Just add the X's (5x + x)=6x, since there is only one whole number without any variables you dont have to do anything to it. So 6x + 3 is your answer.
Answer:
x=-1/2
Step-by-step explanation:
x+3+5x
you would combine like terms so x and 5x
that would give you 3+6x=0
so you minus your 6x, 3=-6x
you then divide by -6 which gives you x=-1/2
or if you were just simplifying it then it would be 3+6x
