Which linear technique would be best to solve this problem? 3x/4 + 6 = -12

And which quadratic equation would be best for -4x^2=0

Thanks for any suggestions.

    I'm confused do you want an answer or what to know what technique would be best?

    1. I suggest using the common factor and canceling out the bottom number.
    Therefore, the common factor is 4. Multuply each one by 4 such as 3x/4 and 6 and also -12. As a result, the 4 crosses out.

    --> (4) 3x/4 + (4) 6 = (4) - 12
    --> 3x + 24 = /48
    --> 3x = - 72
    --> x = - 24

    2. You have to divide by -4 and x^2 = 0 and then the square root of 0 is always 0.

    I would/could have done the work. I just didn't know which technique is best. The name of the technique. Thank you for your help!
