Question

જો ગુ.સા.અ. (25.15)=4x+1હોય તો x=❔​

Answer 1

$Given \: H.C.F( 25,15) = 4x + 1$

Finding H.C.F of (25,15 ):

25 = 5 × 5

15 = 3 × 5

$\green { H.C.F \:of \: 25, 15 = 5 }$

$Now , H.C.F (25,15) = 4x + 1$

$\implies 5 = 4x + 1$

/* subtract bothsides of the equation by 1 , we get*/

$\implies 5 - 1 = 4x + 1 - 1$

$\implies 4 = 4x$

$\implies \frac{4}{4} = \frac{4x}{4}$

$\implies 1 = x$

Therefore.,

$\red{ Value \: of \:x } \green { = 1 }$
