Answer 4

when I subtact the 5 from the x, would I get 5x?

Answer 5

You would get x-5 because only like terms may be combined.

5 - x = 5x
Experimental fact for all x.
(Kidding, of course.)

Answer 7

I got x = x^2 + 18 .. is that correct?

Answer 8

i got x+7=x^2+10x-25

Answer 9

@Ello_M8! Let the asker answer the questions.

Answer 10

The right side should be x^2-10x+25

Answer 11

I was wondering if i did it right :(

Answer 12

ok so now i got x^2-9x18

Answer 13

x^2-9x+18

Answer 14

You should have:
