2/5x - 5/2x = 1/10

4x -25x / 10x² = 1/10

-210x = 10x²

10x²+210x = 0

10x(x + 21) = 0

10x = 0 or x+21 = 0

x= 0 or x = -21

but here X= 0 is rejected as by substituting this we get zero in the denominator which is not defined.

so,

x= -21


priya427326: how did 210 come to this answer
shantanu786: by cross multiplication
priya427326: oo thanks
shantanu786: I've just skipped a step
