4x - (9 - 3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1
-9 + 1 = 8x - 7x
-8 = x

x = -8

Honors Math, do not fail me now. the answer is x = -8 First, the parentheses, -(9-3x) this may get replaced to -(9+-3x) then to -9+3x now you've... 4x+-9+3x=8x-a million Subtract 4x from each and each and every section... , replace 4x-a million to 4x+-a million Now that's... -9+3x=4x+-a million upload a million to each and each and every section... -8+3x=4x subtract 3 x from each and each and every section and now you get -8=1x or -8=x -8 is your answer

4x-(9-3x)= 8x-1
4x-9+3x=8x-1
7x-9=8x-1
-8=x
4(-8) - 9 + 3(-8) = 8(-8) -1
-32-9-24 = -64-1
-41-24=-65
-65=-65

Hope this helps!

4x - (9 - 3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1

7x - 9 - 8x = 8x - 1 - 8x

- x - 9 = - 1

- x - 9 + 9 = - 1 + 9

- x = 8

-1(- x) = - 1(8)

- (- x) = -8

x = - 8

- - - - - - - - - -s-

First distribute the minus sign in front of the parenthenses.
4x-9+3x+8x-1
Then combine like terms on each side.
7x-9=8x-1
Then solve for "x."
-8=x

4x-(9-3x)=8x-1
4x-9+3x=8x-1
7x-9=8x-1
-x-9=-1
-x=8
x=-8

Check:
4(-8)-(9-3(-8))=8(-8)-1
-32-(9+24)=-64-1
-32-33=-64-1
-65=-65
