I M STUCCK, not lazy i've spent like 30 mins thinking about it
2006-06-29 00:14:45 · update #2
can someone explain how to do
8x-5(2x+3)-(1-6x)= 8+(4+6x)
and
3(5x-4)-7(2x-3) = 3(x+1)+5
2006-06-29 00:32:37 · update #3
=> 14x -8+5-9x=1-3x
=> 14x-9x+3x=1+8-5
=> 8x=4
=> x=4/8=1/2=0.5
CHEERS!

Simplify the equation:
14x - 8 + 5 - 9x = 1 - 3x
(14x - 9x) - 8 + 5 = 1 - 3x
5x - 3 = 1 - 3x
5x - 3 + 3x = 1 - 3x +3x
8x - 3 = 1
8x - 4 = 0
8x = 4
x = 1/2

14x -8 + 5 - 9x = 1 - 3x
(14x-9x) -8+5 = 1-3x
5x- 3 = 1-3x
5x+3x = 1+3
8x = 4
x = 4/8
x= 1/2.
(it was the simplest question i ever did)
how old are u dude ?? Because this is a question which even a 10 yr old boy can do. (atleast in my country)

14x - 8 + 5 - 9x = 1 - 3x
14x - 9x + 3x = 1+8-5
8x = 4
x = 4/8
x = 0.5

expand the quesion by multiplying the 2 into (7x-4) then move all the x-s to one side,
14x - 8 + 5 - 9x = 1 - 3x
14x - 3 - 9x = 1 - 3x
14x - 9x + 3x = 1 + 3
8x = 4
x = 0.5

2(7x-4) + (5-9x) = 1-3x
14x - 8 + 5-9x = 1- 3x
14x -9x +3x =1+8-5
8x = 4
x = 0.5

2(7x-4) + (5-9x)=1-3x
14x - 8 + 5 - 9x =1-3x
14x-9x+3x = 1+8-5
17x - 9x = 9 - 5
8x = 4
x= 4/8
x= 1/2

first you mulitply first
(14x-8) + (5 -9x) = 1-3x
then you take out the brackets.
14x -8+5-9x = 1-3x
5x-3= 1-3x
bring over -3x to the left, and -3 to the right. ( the sign changes to positive when it is brought over)
5x+3x= 1+3
8x = 4
x= 0.5
