You can check them by plugging x back in.

2 * 0 = 2

No.

13 + 5 = 17

No.

Can you check the last one?

2 * 0 = 2

No.

13 + 5 = 17

No.

Can you check the last one?

1) 2x=2

For this question, what operation can you do that would isolate x? Since the coefficient of x is 2, then divide both sides by 2.

2x/2 = 2/2

x = 1

2) x+5=17

What operation would get x alone here?

To have x alone on its side, subtract 5 from the left side of the equation to remove the 5

But remember, for these types of questions you need to keep the equation balanced, so you must subtract 5 from the other side as well

x + 5 - 5 = 17 - 5

x = 12

Do the last question and maybe some other for us to check your work.

my answer: x=0

Look at it this way, Black Cat:

if 2 apples cost $2, how much does one apple cost?

2x=2 works same way: if 2 x's equal 2, what does 1 x equal?

2) x+5=17

my answer: x=13

both sides must equal SAME thing; what must be added to 5 to give 17?

YES: it's that simple....

Ironically, I do Have a Black Kitten..but anyway 17-5 is 12 so x would equal 12.and thats all?I thought there was more.Denis said:

x=10 ?Denis said:YES, that's all...quit complicating things!

Ok let's see your "x-rated" abilities now:

2x + 3 = 13 : what's x?

Divide 10 by 2 so that x=5 ?

YES Black Cat.~Midnight.Kitten~ said:Divide 10 by 2 so that x=5 ?

If 2 x's cost 10, how much does 1 x cost?

We told you that before...whatdo you not understand?

if 5a = 40, then a = 8

(if 5 apples cost 40 cents, then 1 apple costs 8 cents)

When you see something like 5x, don't get all nervous!

All it means is 5 "something"
