I really need some help, I have a headake and forgot how to solve for X please help me. :((

Question

anonymous · Answer

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

anonymous · Answer

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

myininaya · Answer

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

parthkohli · Answer

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

anonymous · Answer

25?

myininaya · Answer

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

myininaya · Answer

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.

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

anonymous · Answer

If If m ∠ 3 = 104˚, what is m ∠ 8?

parthkohli · Answer

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

anonymous · Answer

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

parthkohli · Answer

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

anonymous · Answer

Sorry forgot how to do this >.<

parthkohli · Answer

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

anonymous · Answer

So they all equal 104?

parthkohli · Answer

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

anonymous · Answer

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

anonymous · Answer

<2 is going to measure the same as <8

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

*the same as <8

anonymous · Answer

<2

parthkohli · Answer

<3

anonymous · Answer

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