## rannsan 3 years ago solve for x: 7x+2y=5

1. lgbasallote

subtract 2y from both sides 7x = 5 - 2y divide both sides by 7 x = (5-2y)7 does that help?

2. lgbasallote

that should be x = (5-2y)/7

3. rannsan

I think so

4. lgbasallote

@ashna it's solve for x

5. rannsan

I am totally confused now

6. lgbasallote

@rannsan just follow what i said above

7. ashna

7x+2y=5 Subtract the 2y on both sides 7x=-2y+5 Now divided both sides of the equation by 7 x=(-2/7)y+5/7

8. rannsan

x=(-2/7)y+5/7 ?

9. rannsan

I still am not following

10. waterineyes

Let us go step by step: Subtract 2y both the sides first.. Can you do this @rannsan

11. rannsan

trying, this is my first algebra class and it has totally confused me

12. waterineyes

See I give you similar example: Suppose we have: 5x+4y=10 Now subtract 4y both the sides: |dw:1344575744194:dw| Now to find x we must get rid of 5 attached to it so divide by 5 both the sides: |dw:1344575819560:dw| Getting @rannsan

13. rannsan

subtract 2y from what?

14. waterineyes

From both the sides.. Just see the example above and follow the similar steps..

15. waterineyes

There I have subtracted 4y both the sides but in original question you have to subtract 2y from both the sides..

Well Done..

did I get it right?

20. waterineyes

Absolutely right.

21. rannsan

OMG my first correct problem ever thank you so much.................
