Question

plz answer this as fast as you can........

Answer 1

Answer:

1/X+1 + 1/X+2 = 2/X+10

==> X+2+X+1 / (X+1)(X+2) = 2/X+10

==> 2X+3 / X²+2X+X+2 = 2/X+10

BY CROSS MULTIPLY

==> (2X+3)(X+10) = 2(X²+3X+2)

==> 2X²+20X+3X+30 = 2X²+6X+4

==>  23X + 30 = 6X + 4

==> 23X-6X = 4-30

==> 17X = -24

==> X = -24/17

Answer 2

Answer:

-26/17

Step-by-step explanation:

1/(x+1)+1/(x+2)=2/(x+10)

=> (x+2+x+1)/(x.x+3x+2)=2/(x+10) [L.C.M.]

=> 2x.x+6x+4=2x.x+23x+30 [Cross Multiplication]

=>6x-23x=30-4

=>-17x=26

=>17x=-26

=>x=-26/17
