Answer 3

What do I do now?

Answer 4

R u there

Answer 5

You have a mistake in the third line already. I'll help.

Answer 6

thank you

Answer 7

After your second line, you should end up with:

3x=2x-9

Now, you need to subtract 2x from both sides of the equation to get rid of the 2x on the right side.

3x-2x=2x-9-2x

Answer 8

Which leaves you with x=-9

Answer 9

ok thank you

Answer 10

The shortcut is to move the term to the other side of the equation, but you have to change the sign.

In 3x=2x-9, you can move the 2x term to the left side of the equation, but you need to change it from a + to a -.

3x-2x=-9
x=-9

Answer 11

You're welcome. Take care.

Answer 12

ok
you 2

Answer 13

Can you help me with 6(x-4)=3(3x+5)

Answer 14

6x-24=9x+15
-24+15=9x-6x
-9=3x
-3=x
Is this correct?

Answer 15

did i do this right

Answer 16

Nope. Remember when you move a term from one side of an equation to the other, you need to change the sign.

Answer 17

So, you're second line should be:
-24-15=9x-6x <---- a negative before the 15

Answer 18

6x-24 = 9x+15
-24-15 = 9x-6x
-39 = 3x
x = -39/3
x = -13
