Algebra help please show me how you did it?

Question

how do i do this problem

please tell me how you do it too

1/3(as in over 3)x=12

Answer 1

1/3x = 12

multiply the denominator 3 times 3 to cancel it out.

then multiply the 12 times 3 (becuase you have to do the same thing to both sides)

that gives you

1x = 36

x = 36

20 + 50w = 350 -10

-20                    -20

50w = 320

w = 6.4

Answer 2

(1/3)x=12

    x/3=12       multiply both sides by 3

       x=36

or is it

1/(3x)=12      multiply both sides by 3x

      1=36x            divide both sides by 36

   1/36=x

20+5w=350-10

20+5w=340        subtract 20 frm both sides    

     5w=320       divide both sides by 5

       w=64

Answer 3

1/3X = 12

-1/3   -1/3

X = 35/3

You have to subtract both sides by 1/3 to get x alone. This leaves you with x = 35/3

You do the same thing with this one. You have to get W by itself.

20+5w=350-10

You can subtract 10 from 350 first, so now you have:

20+5w = 340

Subtract 20 from both sides, you get:

5w = 320

Now, divide both side by 5 (variable you are left with by W and its being mulitplied so ou do the opposite)

Leaves you with:

W = 64

Answer 4

times each # by the highest common denominater.

EX.  1/3 x 3 = 12 x 3

        x=36

w=64

Answer 5

First things first, let's do 1/3x=12. I'm not going to give you the answer, but you need to get the x by itself. In order to do that, you need to use the LCD (least common denominator). Whenever you're dealing w/ getting rid of a fraction, use the LCD, which in this case would be 3. Multiply 3 by both sides of the equation.  

(3) 1/3x= (3)12.

The 3's in the first 1/2 of the equation cancel out and leave you with just x. Then on the other side, you multiply 3 by 12. So x=36.

For the 2nd one, 20+ 5w= 350-10, you need to simplify a little. Add the terms to the right of the = sign together. So then you have

20+ 5w= 340

You need to get the W isolated (all alone). So, subtract 20 from both sides.  

5w=320    Divide both sides by 5.

w=65

Good luck! And never be afraid to ask your teacher/professor for help if you don't understand.

Answer 6

1/3*x=12

x/3=12

x=12*3

x=36

20+5w=350-10

20+5w=340

5w=340-20

5w=320

w=320/5

w=64
