## ineedyouubiebs 2 years ago What is the value of x in the following system: y=2x+5 y=-3x+10

1. dpaInc

ok.... since both equations start off as "y=..." set them equal to each other....

2. ineedyouubiebs

what do you mean equal to each other?

3. dpaInc

2x+5 = -3x+10

4. ineedyouubiebs

OHHHHH!! OK I got x=-3

5. dpaInc

no... try again.... be careful...

6. ineedyouubiebs

x=3

7. dpaInc

how did u get that? try again...

8. ineedyouubiebs

okay so i got 2x+15=-3x and then i subtracter -2 from -3 on the other side

9. dpaInc

ok... you moved the 10 over from the right side so that means you needed to SUBTRACT 10 from both sides... that 15 should be a -5... ????

10. ineedyouubiebs

OHHHHH! SORRY!! I forgot to do inverse operation !

11. dpaInc

so let's take it from there now.... 2x - 5 = -3x what next?

12. ineedyouubiebs

you subtract -2 from -3x

13. dpaInc

you mean subtract 2x from both sides.... ??? 2x - 5 -2x = -3x -2x

14. dpaInc

can you simplify both sides??

15. ineedyouubiebs

16. dpaInc

you're solving for x so you do not want to cancel x.... cancel the -5 instead...|dw:1360045928707:dw|

17. dpaInc

now solve for y....

18. ineedyouubiebs

ok its y=2

19. dpaInc

how did u get that? you can use either equation from the beginning....

20. dpaInc

just plug in x=1 to either equation to find y...

21. ineedyouubiebs

yeah that's exacly what i did @dpaInc oohh wait i checked it and i got 7 now

22. dpaInc

lol... that's correct now...

23. ineedyouubiebs

YAYxD they are asking for the value of x and in the beggining we talked that it was x=1

24. dpaInc

oh... you didn't need to find the value for y ???

25. ineedyouubiebs

no.but that's alright dont worry.thanks so much,i suck at algebra so i really need all the help i can get=D

26. dpaInc

you don't suck at algebra.... just need practice like everyone else.... keep up the good work... cya! :)
