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

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

    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

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

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

    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.

    If If m ∠ 3 = 104˚, what is m ∠ 8?

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

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

    No... first use \(\angle 3 = \angle 7\).

    Sorry forgot how to do this >.<

  15. ParthKohli

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

  16. AngelLeigh-Anne

    So they all equal 104?

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

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

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

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

  32. AngelLeigh-Anne
    • 2 years ago

    so they are all 104

  33. jazy
    • 2 years ago

    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.

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

  35. jazy

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

    So 104 + ? = 180
