Question

पुढील समीकरणासाठी Dची किमत काढा 5x+3y+11=0;2x+4y=-10​

Answer 1

Answer:

D = 14

Step-by-step explanation:

In equation 5 x +3y+ 11= 0 and 2x + 4y - 10 = 0

A1 = 5 , B1 = 3 , C1 = 11 and A2 = 2 , B2 = 4 , C2 = -10

D = A1. B1. } cross multiple

A2. B2. } cross multiple

= 5. 3

2. 4

= 5×4 - 2×3

= 20 - 6

= 14

पुढील समीकरणासाठी Dची किमत काढा. 5x+3y+11=0;2x+4y=-10

-----------------------------------------------------------

5x + 3y +11 = 0

5x + 3y = -11--------( 1 )

2x +4y =-10 --------( 2 )

D = / a1 b1 /

/ a1 b2 /

D = / 5 3 /

/ 2 4 /

D = (5 × 4 )- ( 3 × 2 )

D = 20 - 6

D = 14

Dx = / c1 b1 /

/ c2 b2 /

Dx = /-11 3 /

/ -10 4 /

Dx = ( -11 × 4 ) - ( 3 × -10 )

Dx = -44 - ( -30 )

Dx = -44 + 30

Dx = -14

Dy = / a1 b1 /

/a2 b2 /

Dy = / 5 -11 /

/ 2 -10 /

Dy = ( 5 × -10 ) - ( -11 × 2 )

Dy = -50 - ( -22 )

Dy = -50 + 22

Dy = -28

क्रेमरच्या पद्धतीनुसार ,

X = dx /d

X = -14/14

X = -1

Y = dy /d

Y = -28 / 14

Y = -2

( X , Y ) = ( -1 , -2 ) ही समीकरणाची उकल आहे .
