Question

(70/x)-(70/x+4)=2 the value of this equation​

Answer 1

Answer:

X=10 or X=-14

Step-by-step explanation:

=>(70/X)-(70/X+4)=2

Taking LCM = x(X+4)

=>(70(x+4)-70x)/x^2+4x =2

Cross multiplication,

=>70x+280-70x=2x^2+8x

=>280=2x^2+8x

Taking all the terms on the same side,

=>2x^2+8x-280=0

Taking 2 common,

=>2(x^2+4x-140)=0

Mid-term Splitting,

=>x^2+14x-10x-140=0

=>X(X+14)-10(X+14)=0

=>(X+14)(x-10)=0

Now,

X+14=0

So, X= -14

Or,

x-10=0

So, X=10
