Do you have a specific problem you need to solve? I can go step by step and help you through it.

2. AngelLeigh-Anne Group Title

4x-31 on one side and 2x+19 on the other solve for x

3. myininaya Group Title

So we have this: 4x-31 = 2x+19 Get your terms that have factor x on one side All other terms, your constant terms, on the other side

4. ParthKohli Group Title

Let's make up an equation and I'd solve it for you:\begin{aligned}6x + 3&=9x - 1\\6x&=9x - 1 - 3\\ 6x&=9x-4\\6x - 9x&=-4\\ -3x&=-4\\ x &={4 \over 3} \end{aligned}

5. AngelLeigh-Anne Group Title

25?

6. myininaya Group Title

How about we have some interaction which includes the user asking here to solve for x?

7. myininaya Group Title

So we have 4x-31=2x+19 Do you know how to put your x terms together and your constant terms together? You need to do this by adding/subtracting terms from both sides.

8. AngelLeigh-Anne Group Title

Okay thanks, I'll post another prolbem, it's really complex and I haven't seen it before

10. AngelLeigh-Anne Group Title

If If m ∠ 3 = 104˚, what is m ∠ 8?

11. ParthKohli Group Title

Hint: use corresponding angles identity, then find a linear pair.

12. AngelLeigh-Anne Group Title

< 2, 3, 6,7 are the same?

13. ParthKohli Group Title

No... first use $$\angle 3 = \angle 7$$.

14. AngelLeigh-Anne Group Title

Sorry forgot how to do this >.<

15. ParthKohli Group Title

Then notice that you have a linear pair, so $$\angle 7$$ and $$\angle 8$$ are supplementary.

16. AngelLeigh-Anne Group Title

So they all equal 104?

17. ParthKohli Group Title

Hmm, do you know what these are? 1) Corresponding angles 2) Alternate interior angles 3) Linear pair 4) Opposite angles

18. AngelLeigh-Anne Group Title

Yeah I'm a sinor, but I forgot it's been like a year since I was in math

20. AngelLeigh-Anne Group Title

Ohhhh

21. AngelLeigh-Anne Group Title

Um. So it's not 104

22. AngelLeigh-Anne Group Title

it's 94?

23. AngelLeigh-Anne Group Title

>.<

24. jazy Group Title

|dw:1350654253156:dw|

25. AngelLeigh-Anne Group Title

<2 is going to measure the same as <8

26. AngelLeigh-Anne Group Title

half of 180 is 90, but that's not an answer choise

27. jazy Group Title

Yes. <2 is the same as 8. They give you angle 3, 104 degrees. What other angles are the same as angle 3?

28. jazy Group Title

*the same as <8

29. AngelLeigh-Anne Group Title

<2

30. ParthKohli Group Title

<3

31. jazy Group Title

No, angle 2 and 3 are supplementary. Added up they equal 180 degrees. |dw:1350654491698:dw|

32. AngelLeigh-Anne Group Title

so they are all 104

33. jazy Group Title

No, angles 3, 1, 5, 7 are all corresponding. So if angle 3 is 104 degrees, then so are 1,5,7. Do you understand? Angles 2, 4, 6, 8 are also corresponding to each other.

34. AngelLeigh-Anne Group Title

Yeah I understand but how to I find out how much the other angles are

35. jazy Group Title

Supplementary angles form 180 degrees. A straight equals 180 degrees. |dw:1350654810017:dw|

36. jazy Group Title

So 104 + ? = 180

37. AngelLeigh-Anne Group Title

I got my test wrong anyways. Sorry, thanks for the help

38. jazy Group Title

Sorry to hear that. ):
