Question

Is this correct?

question: What is the solution of 5 - 2x > -3 or -3x + 9 < -6?

my answer:
5 - 2x > -3 OR -3x + 9 < -6



5 - 2x > -3

5 - 2x - 5 > -3 - 5

-2x > -8

-2x/-2 > -8/-2

x > 4



-3x + 9 < -6

-3x + 9 - 9 < -6 - 9

-3x < -15

-3x/-3 < -15/-3

x < 5



The solution to this inequality is x > 4 and x < 5, so the solution is all real numbers.

Answer 1

when you divide both sides by a negativ number in case of an inequality this sign need chenging invers

Answer 2

so the first one not is right

Answer 3

5-2x>-3 add to both sides 2x so what will get ?

Answer 4

please collaborate

5 > -3+2x than add to both sides 3 and will get

5+3 > 2x

8>2x divide both sides by 2 and will get

4>x

hope helped

Answer 5

so the second one is the same with the first not right

hope you can correct it now

Answer 6
