Question

Hey, I need to solve the inequality:

2x+3<2(x+3)
0<0
So the answer is (-infinity;+infinity)? Or there is no Real solutions to this equation? It is a bit confusing for me, because how 0 can be a smaller number than 0 (according to the problem)?

Answer 1

@hartnn

Answer 2

to this inequality*,sorry,I am still sleeping;D

Answer 3

its not 0<0

distribute 2 to (x+3)
for simplifying
\(2(x+3)\)

and it is not same as 2x+3

Answer 4

uhh:o sorry! Then I know how to solve. Whats about this one:

6x+7>2(3x+4)
6x-6x>8-7
0x>1

(hopefully no arithmetic mistakes now;D)

Answer 5

nah, I dont know still how to solve that one too;D

Answer 6

Do the same thign.

Answer 7

0>1
never true, right?

so no solution :)

Answer 8

and the first one is 0x<3 so x e (-infinity;+infinity)?

Answer 9

thats right :)

Answer 10

because 0 is always smaller than 3?

Answer 11

thankyouu:}
