solve: 2 absolute value of x minus 3 =7

Question

anonymous · Answer

yes

mertsj · Answer

$$2|x-3|=7$$

mertsj · Answer

Divide both sides by 2
|x-3|=7/2
x-3=7/2 or x-3=-7/2
Solve both equations.

anonymous · Answer

how do u solve it thats what i dont understand

mertsj · Answer

Add 3 to both sides of the equations I have written.  Can you add 3 to 7/2?
Can you add 3 to -7/2?

anonymous · Answer

no u get a fraction

mertsj · Answer

Yes.  Sometimes in mathematics, you will have answers that are fractions.

anonymous · Answer

i know but the answers i have are not answers on my worksheet

mertsj · Answer

3 + 7/2=3+3 1/2=6 1/2=6.5
3-7/2=3-3 1/2=-1/2=-.5

anonymous · Answer

the answers on my sheet are: x=-10,x=10. x=-2,x=2. x--5,x=5. or x=-8,x=8.

mertsj · Answer

So if that is the case, I have not interpreted your problem correctly and the equation editor is not working.  Is your problem 2 times the absolute value of (x-3)=7 or is it something else?

anonymous · Answer

my problem is 2 absolute value of x. (x by itself.) minus 3 =7

mertsj · Answer

Ok.  Add 3 to both sides

mertsj · Answer

Then divide both sides by 2.

I'm going to restart my browser.  Maybe things will work better.

mertsj · Answer

mertsj · Answer

anonymous · Answer

mertsj · Answer

x=5 or x = -5
