X+2=X+2? what is the answer?

Question

X+2=X+2? what is the answer?

Answer 1

the answer is zero because the 2's cancel out and then there's zero....

Answer 2

well the twos cancel each other out if you do the opposite of addition and subtract from both sides and same goes for x. so your answer is 0

Answer 3

42

Answer 4

X can be any number.

Answer 5

x+2=x+2

(x+2)=(x+2)

(x+2)=a

a=a

True for all a.

Thus, x+2 can be anything, therfore, x can be anything.

Subtract two from each side to get:

x=x

Subtract x from both sides to get:

0=0

This is always true therefore x is any number.

x+2=x+2

Associative property to get:

x+2=2+x

Stated by the commutative property.

Properties are true for all x.

x+2=x+2

at x+2=0, x=-2 so check x=-2 to see if its valid.

0=0 true so x=-2 is valid.

Hence to figure if x=-2 is the only solution or not, divide by (x+2) we know we can do this because x is not -2 and x+2 is not 0 for this case.

So,

(x+2)/(x+2)=(x+2)/(x+2)

a/a=1 unless a=0 which we have eliminated.

So,

1=1

identity, therfore, it is true for all x.

x+2=x+2

check x=0

2=2

x=1

3=3

x=4

6=6

x=98

100=100

so x is all real numbers, because 0=0 will be the resulting equation.

x+2=x+2

-x-2=-(x+2)

So,

-(x+2)+x+2=0

Therefore:

-x-2+x+2=0

[x-x]+[2-2]=0

0+0=0

0=0

True again, therefore x can be anything.
