## LonelyandForgotten Can someone teach me how to solve an equation with variables on both sides? i need help :( one year ago one year ago

1. myko

2x+3=4x-4 like this?

2. LonelyandForgotten

yeah something like that

3. myko

put all that have x one side and that have not , to the other

4. hisgirl2012

What is the equation you're trying to solve?

5. matineesuxxx

myko is right, but when you move a number to the other side of the eual sign you need to change the sign of the number itself. 4 becomes -4 and -4 becomes 4

6. LonelyandForgotten

well i understand that part but i cant go on further, i always get stuck :(

7. myko

after you got something like this: ax=b do this: x=b/a andyou are done

8. matineesuxxx

so now how would you solve 4x=18?

|dw:1362524358288:dw| I dont know if this is right or wrong but i dont know where to go from there :/

10. LonelyandForgotten

that is the problem i am working on now

11. hisgirl2012

If you're getting the "X's" on one side then make sure you include the x. You're combining like terms. So it would be +3x under the -3x and the -7x. But you got it right so far after you get there your going to combine the +2 and the -22.

12. LonelyandForgotten

okay i can go on from there, thanks for your help :)

13. hisgirl2012

No problem.

|dw:1362525009117:dw| Is this right?

15. ghazi

nope

16. LonelyandForgotten

ghazi :D

17. LonelyandForgotten

hi :D

18. ghazi

:D BP hey ;)

19. LonelyandForgotten

can you help me please :(

20. ghazi

BP i am :D

21. ghazi

-3x + 2 = -7x-22 now bring like terms at one side so terms with variable lets say the ones with "x" bring them together and numbers together ;) so -3x+7x=-22-2 4x=-24 now divide both sides by 4 and you will have x=-6 $\frac{ 4x }{ 4 }=\frac{ -24 }{ 4 }$ so x= -6 ;)

22. ghazi

|dw:1362525310743:dw| clear?

23. LonelyandForgotten

wait.. how did you do that? :/

24. LonelyandForgotten

i think you are missing something

25. ghazi

nope i did , just bring 4x in the left so sign will be changed and take +2 on the right so sign will be changed and it will be +4x and on the right it will be -2 because sign gets interchanged
