Solve the following Simultancous equation by substitution method
8x+5y=9,2y= -3x+4
​

Answer 1

Step-by-step explanation:

2x−5y=9 -----(1)

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

from equation (1)

2x−5y=9

y= 2x-9/5

substitute the balue of y in equation (2)

5x+6( 2x-9/5)=8

25x+18x−54=40

43x=40+54

43x=94

x= 94/43

Substitute the value of x in equation (1)

2( 94/43)−5y=9

188−215y=387

188−387=215y

y= 199/215

Therefore solution is x= 94/43

and y= 199/215
