I need help with mi algebra homework wat iz 7x-4=20+3x?

Question

u need to tell me how u got tha answer 2 get tha 10 points

Answer 1

7x-4 = 20+3x right?

first you must add 4 to both sides

thus the -4 and the 4 cancel out on the left side.

7x = 24 + 3x

Next, subtract 3x from both sides.

Thus the +3x - 3x = 0 on the right side

4x = 24

x = 6

Answer 2

it is simple

collect all the x terms on one side and everything else on other

7x-4=20+3x

7x-4 -3x = 20

7x-3x = 20 + 4

4x = 24

x = 24/4

x = 6

Answer 3

7x-4=20+3x

   +4  +4            (add four to both sides to isolate x)

7x= 24+3x

-3x      -3x          (subract 3x from both sides)

4x=24

now divide both sides by 4 to get x by itself

x=6

Answer 4

haha i didn't know it was domyhomework.yahoo.com lol i thought i am surfing answers.yahoo lol.

anywayz here it iiz:

7x-4=20+3x/+4

                /-3x

4x=24/:(4)

x= 6

Answer 5

Put like terms on a separate side, and remember to change the sign when you move to another side:

so, 7x - 4 = 20 + 3x

then, 7x - 3x = 20 + 4

        4x = 24

         x = 24/4

         x = 6
