6(x+3) + 3x = 3(x-2)
--> expanding all brackets
6x + 18 + 3x = 3x - 6
9x + 18 = 3x - 6
9x + 18 - 18 = 3x - 6 - 18 (subtract 18 from both sides)
9x = 3x - 24
9x - 3x = 3x - 3x - 24 (subtract 3x from bth sides)
6x = -24
6x/6 = -24/6 (divide by 6)
x = -4
Ans: x = -4

next, a = 3, b = 2, c = -a million a * c -> 3 * a million = 3 Use the elements of three which have a distinction of "b"(it really is a distinction because the signal of the third time period is a unfavourable image. if it became a good image then the product would ought to operate as a lot as b). a million * 3 = 3 3 - a million = 6622ab62d8cbb4572c1b1ca2c635a33f3x^2 + 2x - 16622ab62d8cbb4572c1b1ca2c635a33f3x^2 + 3x - 1x - a million) 3x [ (3x^2 + 3x) + (-1x - a million) ] 3x [ 3x*(x + a million) - a million(x + a million) ] 3x * (3x - a million) * (x + a million)

6x +18 +3x = 3x -6
multiply the boxes out
9x +18 = 3x -6
add the common values
9x-3x = -6 - 18
numbers on one side, letters one the other
6x = -24
do the actions
6x/6 = -24/6
divide by 6 because you want x
x = -4

distribute then combine like terms.
Move all of the x's to one side and all of your integers to the other.
combine like terms and divide by the integer in front of the x.
Practice is the best way to learn!

Do your own homework. That's the only way you'll be able to understand it. If you need help ask for it from parents,teachers,friends or adults. Make sure you understand it for yourself!
