    Step-by-step explanation:

    First, distribute the outside numbers into the parentheses:

    5*x+5*-12+6=3*2x+3*-7

    5x-60+6=6x-21

    Combine like terms

    5x-54=6x-21

    Add 21 to both sides

    5x-33=6x

    Subtract 5x from both sides

    you wind up getting x=-33

    x=-33

    you can check to make sure that's the correct answer but simply plugging in - 33 for x and checking to make sure both sides of the equation are equal:

    -33-12=-45*5=-225+6=-219

    -33*2=-66-7=-73*3=-219

    So, yes, x equals - 33

    You distribute the 5 and times it by x and - 12 then the problem would look like this

    5x-60+6=3 (2x-7)

    next you distribute the 3 and times it with 2x and - 7 then the problem would look like this

    5x-60+6=6x-21

    then you solve by combining like terms on the left so you minus 6 from 60 and get 54 so now you have

    5x-54=6x-21

    now you add 54 to - 21 but since it's a negative you will subtract and take the larger numbers side which will be 33

    now you have a problem that looks like this

    5x=6x+33

    so now you subtract 6x with 5x and get 1x

    so the problem will look like this

    1x = 33

    then you divide 1x on both sides and the answer is

    x = 33
