Question

x+2/x-1=5/2, x=3 सत्यापित कीजिए चर का दिया गया मान निम्न समीकरण का हल हैं या नहीं​

Answer 1

Answer :-

$\frac{x + 2}{x - 1} = \frac{5}{2}$

$2(x + 2) = 5(x - 1)$

$2x + 4 = 5x - 5$

$2x - 5x = - 5 - 4$

$- 3x = - 9$

$x = \frac{9}{3}$

$x = 3$

Hence verified.

Answer 2

x+2

=

2

5

2(x + 2) = 5(x - 1)2(x+2)=5(x−1)

2x + 4 = 5x - 52x+4=5x−5

2x - 5x = - 5 - 42x−5x=−5−4

- 3x = - 9−3x=−9

x = \frac{9}{3}x=

3

9

x = 3x=3

Hence verified.
