Multiply out the 3(x+6) to get 3x+18:
So now you have:
3x + 18 + 6x = 7x + 2
Let's get all the "x's" to one side: I'll subtract 7x from both sides:
3x + 18 + 6x -7x = 7x + 2 - 7x
This results in (add up the like terms):
2x + 18 = 2
subtract 18 from both sides:
2x = -16
divide by 2:
x = -8

hey its very simple:
q: 3(x + 6) + 6x = 7x + 2
=> 3x + 18 + 6x = 7x + 2
=> 9x + 18 = 7x + 2
=> 2x = -16
=> x = -8

First, aspect out an x x(3x^2 - 7x - 6) = 0 Now aspect the trinomail x(3x + a million)(2x - 3) = 0 Set each and each area = 0, then clean up x = 0 3x + a million = 0 3x +a million - a million = 0 - a million 3x = -a million 3x/3 = -a million/3 x = -a million/3 2x - 3 = 0 2x - 3 + 3 = 0 + 3 2x = 3 2x/2 = 3/2 x = 3/2 X = 0, -a million/3 and three/2

3x + 18 + 6x = 7x + 2
3x + 6x -7x = 2 -18
2x = -16
x = -8

3 (x + 6) + 6x = 7x + 2
3x + 18 + 6x = 7x + 2
3x + 6x + 18 = 7x + 2
9x + 18 = 7x + 2
9x - 7x = 2 - 18
2x = -16
x = -16 / 2
x = -8

3(x + 6) + 6x = 7x + 2
3x + 18 + 6x = 7x + 2
3x + 6x - 7x = 2 - 18
2x = -16
x = -16/2
x = - 8

X = -8
multiply and solve
3x + 18 + 6x = 7x +2
6x + 3x = 9x
so the problem looks like this
9x + 18 = 7x +2
-7x -7x
--------------------
2x + 18 = 2
-18 -18
-------------------
2x = -16
x = -8
