Question

Solve for x: -2(x + 3) = -2(x + 1) - 4

Answer 1

i solved it & i am now left with -2x - 6 = -2x - 6 ... is the answer all real numbers or no solution?

Answer 2

i think you have done something wrong while solving cauze 0=0 is not a solution

Answer 3

but its okay cus the choices i have for the problem are


All real numbers
3
2
No solution

Answer 4

then you should go with no solution

Answer 5

you did it right, and go with all real numbers
plug a few in and see

Answer 6

ok im confused, no solution or all real numbers?

Answer 7

Your equation will finally become f(x)=0 which for every real number has a solution at 0.

Answer 8

No matter what x you put in, your function will remain 0.

Answer 9

if \[x \in \mathbb{R}\]

Answer 10

its no solution cauz its not satisfying left hand side and right hand side.

Answer 11

It does satisfy left hand and right hand, 0=0 is valid.

Answer 12

and no matter what real number you put into x, it will satisfy both left and right hand, try it out.

Answer 13

If you solve the equation it will finally boil down to x=x --> 1=1 --> 0=0

Answer 14

plug some in and see for yourself...
-2(1+3) = -2(1+1)-4 ?
-2(97+3) = -2(97+1)-4 ?
-2(-5+3) = -2(-5+1)-4 ?
try as many as you like, they will all work

Answer 15

listen bro i mean to say that X is not yielding any value we have to find a particular solution for X we here satisfying the factors for x

Answer 16

so where does it cross the X axis? Everywhere!!!

Answer 17

;)

Answer 18

now i m going to solve your question with every step
-2(x+3)=-2(x+1)-4
-2x-6=-2x-2-4
-2x-6=-2x-6
both sides will be cancelled
what we have to find was the particular value of x since X has been cancelled from both sides so we got no value of X and so this equation has no solution. And for your info i have asked my teacher too about this problem and teacher said that its a no solution eq
