Please help me with this math problem: 3(x-1) > 2(x+1/2)?

Please check if I did everything correctly:

Problem: 3(x-1) > 2(x+1/2)

3x-3 > 2x+1

+3 +3 (Added the 3 to the 1)

3x > 2x+4

And then would I have to do 3x/2x?? That would be 1.5…

Tthen there would be no x then…

I’m stuck here, please help! Thanks.

3x-3>2x+1

3x-3+3>2x+1+3

3x>2x+4-2x

3x-2x>4

x>4

you dont divide by 2x you do the opposite. since it is a positive 2x you subtract 2x on both sides leaving you with 1x or just x.

Once you have 3x > 2x + 4 just subtract 2x from both sides of the equation to get

3x – 2x > 2x – 2x + 4 or x > 4

Thanks for showing your work and not just asking someone to solve your problem for you.

This problem is called an inequality, that means your are not trying to get x by itself which is what you were trying to do. rather you want to get all the factor on one side of the equation and the other side would be zero. this would give you 3x-2x+4>0 which turns into x+4>0 and your answer would be x> -4, anything greater than -4 would give you a number greater than zero. i hope this makes sense. let me know if you still need help.

Hello you were right to add 3 to both sides to get:

3x > 2x +4

but you should subtract 2x from both sides not divide.

3x > 2x + 4

-2x -2x

1x > 4 or just x>4

Hope this helps.

You do the opposite but you are not done combining like items first. You are adding the 2x to the four so you need to subtract it to get it on the other side. Only then will you multiply or divide. Once you have x on one side and numbers on the other.
