Can you solve this? The answer is x=-4. I didn't get that answer =[

This is easy.

First let's multiply everything by 4:

5x + 2 = 4x - 2

Now, subtract 4x from both sides:

x + 2 = -2

Now, subtract 2 from both sides:

x = -4

the sum is wrong. It should be 5x/4 - 1/2 =x+1/2.
Then the steps will be
5x/4-x =1/2+1/2
x/4=1
x=4

move both 1/2 to the same side, and move the x to the other side. gives 5x/4 -x = -1 Then convert x to 4x/4 5x-4x = 1x Now you have x/4 = -1 multiply each side by 4 Then x = -4

First you have to wipe out the denominators with 4:
5x+4=4x-2
5x-4x=-2-2
x=-4

5x/4+1/2=x-1/2

5x/4+ 1/2+1/2 =x

5x/4+ 1 =x

5x +4 = x
--------
4


5x + 4 =4x

5x - 4x = -4

x = -4

x=4
5 times -4/4 = -20/4= -5
-5+1/2= -4 1/2
-4...........and junk like that i cant remember i was soo good at math but i forgot how to do it

5x/4+1/2=x-1/2
5x/4-x+1/2-1/2=x-x-1/2-1/2
x/4=-1
x/4*4=-1*4
x=-4

To Check Substitute the X's with -4 and u should get the same answer.

Mark as the best answer please =]

first, write as fractions and multiply the whole equation by 4
then you have 5x + 2 = 4x -2
now move x's to the left
x +2 = -2
and move numbers to right
x = -4

5x/4=x-1/2-1/2
5x/4=x-1
5x=4x-4
5x-4x=-4
x=-4
