Question

solve for x --> (4)/(3x+2) ≥ 0
i don't understand the concept and need an explanation...

Answer 1

you'll solve the same way as you would a regular linear equation except you don't have an equal sign...you have a >= sign

Answer 2

i divide both sides by 4? i'm sorry i really don't understand it.

Answer 3

then how do i get rid of the fraction?

Answer 4

what stumps is that the x is in the denominator

Answer 5

if you divide both sides by 4 your left with just 3x+2>=0

Answer 6

because the 4 on the left will cancel and on the right 0/4 is still 0

Answer 7

how does 1/(3x+2) become 3x+2?

Answer 8

hagn on i'll try and find a good way to explain it

Answer 9

see it doesn't become 1/3x+2....it basically busts the fraction out

Answer 10

and you can do it in reverse....like if i have 3x+2 / 4 > 0...i can multiply out the 4 and get just 3x+2

Answer 11

dividing is inverting and multiplying

Answer 12

so what happens for 1/3x+2 to just flip?

Answer 13

u don't have 1/3x+2....you have just 3x+2

Answer 14

now you just solve for x...move the 2 over to make it -2 and divide by 3

Answer 15

then it becomes x >= -2/3
