Question

can someone explain to me how to do this.
3x+5<2x-8

Answer 1

basically solve just like you would an equation
3x<2x-8-5

Answer 2

3x-2x<-13

Answer 3

x<-13

Answer 4

got it? @mimimarie416

Answer 5

yes thank you so much

Answer 6

what you want to do is put all the x's on one side. So subtract 2x from both sides.

3x - 2x + 5 = 2x - 2x + 8

On the right side 2x - 2x is 0 so you are left with only 8. On the left side 3x - 2x is only x so now this is your new equation.

x + 5 = 8

From here you want to subtract 5 from both sides

x + 5 - 5 = 8 - 5

On the left side 5 - 5 is 0 so you are only left with x and on the right side you subtract 8 - 5 which is 3.

So the final solution is x = 3.

If you want to check to make sure it is right then plug 3 back into the original equation.

3(3) + 5 = 2(3) + 8

9 + 5 = 6 + 8

14 = 14
