Babygirl1971 3 years ago solve 2x+9>x+19 Thanks!!

1. benice

show that you tried it and ill help

2. Babygirl1971

I did try it and I came up with 3x>29, I'm not sure what I'm doing wrong?

3. Babygirl1971

Now I came up with 3x>10

4. benice

ok for example say x is = 50 2x+9>x+19 2(50)>50+19 100>69 100 is greater than 69 ie 100>69 when i was in school the > was called an alligator and would open its mouth to the bigger number it waas greedy so to solve for x 2x+9>x+19 2x-x+9>19 x+9>19 see if you can do the last bit

5. Babygirl1971

Is the x considered 1x or do I just add it to 9 and say 9x>19?

6. benice

what number when added to 9 is greater than 19 yes x= 1x

7. Babygirl1971

So I got this so far 1x+9>19 and x is equal to 11.

8. benice

what age are you? yes very good 11 is a correct answer so too finish it off 1x>19-9 1x>10 like you said 11 work so does 10.0000000000000000000000000000000001 so any number greater than 10
