Question

खालील एक सामायिक समीकरणे क्रेमरच्या पद्धतीने सोडवा.4x+3y=4;6x+5y=8​

Answer 1

Answer:

Given, 4x + 3y - 4 = 0 -------(1)

6x = 8 - 5y

6x + 5y - 8 = 0 -------(2)

use Cramer's rule ,

4x + 3y - 4 = 0

6x + 5y - 8 = 0

for equations ,

=> x/(-24 + 20) = -y/(-32+ 24) = 1/(20 - 18)

=> x/-4 = -y/-8= 1/2

=> x/-4 = y/8 = 1/2

=> x = -4/2 = -2 and y = 8/2 = 4

hence, x = -2 and y = 4
