5x - 4 = 3x - 2
2x = 2
x = 1
Agreed !

10x – 4 – 5x = 6 + 3x – 8 First, we need to transpose. This means that you have to transfer all like terms on one side. In this equation we need to transfer all the terms with "x" and all the numerals.When you transpose a number form one side to another, the sign changes. Let us start. 10x-5x-3x=6+-8+4 ( + beside - is also -) I transfered 3x to the other side so it became -3x. Same with -4 = 4 on the other side. If you are getting confused, let us do this one by one. 10x – 4 – 5x = 6 + 3x – 8 (First go for 3x) 10x-4-5x-3x=6-8 (Then for the number 4) 10x-5x-3x=6-8+4. Now we have: 10x-5x-3x=6-8+4 Combine like terms on both sides: 1st: 10x-5x-3x. Start with the two negatives. (-5x and -3x) Which will become -8x. Then proceed: 10x-8x=2x 2nd: Both positives: 6 and 4= 10 So, 10-8 is 2. For the other side we have: 2x And the other: 2 So, 2x=2 the x must be isolated. and to do that, you must divide both sides by 2. 2x/2=2/2 (2x/2 cancel the two 2 and 2/2 is 1, therefore leaving us with x and 1) The answer is: x=1

Looks right.

10x - 4 - 5x = 6 + 3x - 8
(10x - 5x) - 4 = 3x + (6 - 8)
5x - 4 = 3x - 2
2x = 2
x = 1

You are correct.

the answer is wrong,
u would have to group the numerals
(10x-5x-4)=(6-8+3x)
10x-5x -2+3x
=5x-4
group it
5x+3x-4-2
2x-2
2x


if ur trying to find x
it is equal to 1
because:
(10x1)-(5x1-4)
=10-5=5-4=1

(6+3x-8)
=6+3x1
=9-8=1

10x - 4 - 5x = 6 + 3x - 8
10x - 5x - 4 = 6 - 8 + 3x
5x - 4 = -2 + 3x
5x - 3x = -2 + 4
2x = 2
x = 2/2
x = 1

x=1 you are good in math
2008-02-08 3:41 pm
yep u got the ryt answer.. u good keep it up
2008-02-08 3:29 pm
10x-4-5x=6+3x-8
10x-5x-3x=6-8+4
2x=2
x=2/2
x=1
I get the same answer as you.

u r obviously right..................
