28-(3x+4)=2( x+6)+x
-84+112=2x+12+x
28=3x+12
28-12=3x
16=3x
16/3=x
5.3=x

Answer:

1. x = 2

2. x = -3

Explanation:

1.

28 - (3x + 4) = 2(x + 6) + x

28 - 3x - 4 = 2x + 12 = x

24 - 3x = 3x + 12

-3x -3x

-------------------------

24 - 6x = 12

-24 -24

---------------------

-6x = -12

÷-6 ÷-6

---------------

x = 2

----------------------------------------------------------------------------------------------------------

2.

3(x - 6) + 6 = 5x - 6

3x - 18 + 6 = 5x - 6

3x - 12 = 5x - 6

-5x -5x

--------------------------

-2x - 12 = -6

+12 +12

----------------------

-2x = 6

÷-2 ÷-2

--------------

x = -3

I hope this helps!
