(x+6)-(2x+7) = x-2x + 6-7 = -1x-1
-x-1-3x=-9
-4x-1=-9
-4x-1+1=-9+1
-4x=-8
x=-8/-4
x=2, this is assuming your - was always a minus and not a negative sign and multiplying by dropping a symbol.
Remember PEMBDAS (parthensis, exponent, multiplecaton/divide, add/subtract)

x = 2
(x+6-2x-7-3x = -9) distribute the negative :)

x = 2 because
(x+6)-(2x+7)-3x= -9
x -2x -3x = -9 -6 +7
-4x = -8
x = 2

First, start simplifying things.
(x+6)-(2x+7)-3x=-9
When you add numbers, it doesn't matter what order you add them in, but it is important to distribute the - to the (2x+7). So think of it like this:
x+6-2x-7-3x=-9
then like this:
x-2x-3x+6-7=-9
Now simplify MORE!!
-4x-1=-9
Now put all of the numbers on one side, and the xs on the other:
-4x=-8
THen divide:
-4X/-4=-8/-4
x=2
Tada!
Now, can you do this one:
(3x+2)-(2x+8)+x=-32

take away the parenthesis x+6-2x+7-3x=-9
then combine like terms -4x+13=-9
subtract 13 from both sides -4x=-22
then divide by -4 x=5.5
and there is your answer
