Solve 4/x + 8/x+2 = 4

Mathematics
1 answer:
Trava [24]3 years ago
7 0

Answer:

x = 0 and x = 3

Step-by-step explanation:

I will assume that you mean:

4         8

---- + --------- = 4

 x      x + 2

Here the LCD is x(x + 2).

Multiplying all 3 terms by x(x + 2), we get:

4(x + 2) + 8x = 4(x)(x + 2), or

4x + 8 + 8x = 4x^2 + 8x

Cancelling the 8x terms, we have:

12x = 4x^2, or 3x = x^2, or x^2 - 3x = 0.

Factoring, we get x(x - 3) = 0, which results in x = 0 and x = 3.

River C is 200 miles longer than River D. If the sum of their lengths is 5580 ​miles, what is the length of each​ river?
Valentin [98]

Yo sup??

Let the length of river D be x

then the lenght of river C will be 200+x

but,

lenght of river C+lenght of river D=5580

x+x+200=5580

2x=5380

x=2690

Therefore lenght of river D is 2690 and that of C is 2890

Hope this helps
