Question

solve the equation:3/(x+1) -1/x=1/2

Answer 1

Multiply each term by the common denominator which is 2x(x+1)

Answer 2

Common denominator is x(x + 1) So

After simplifying you should get
(2x -1) / x(x+1) = 1/2

You can cross multiply here and get

2(2x -1) = x(x+1)

Now move everything to left side
2(2x -1) -x(x+1) = 0

Expand and get
-x^2 +3x -2 = 0

-((x - 2)(x -1) = 0

x = 2
x = 1

Answer 3

are you sure?

Answer 4

because after i submit them i cant do it again^.^

Answer 5

Yup, see what happens when you put 2 in for x into the original equation. Then see what happens when you put 1 in for x. You'll always get the right answer. I'm 100 percent positive.

Answer 6

OK:)
