Question

समीकरण हल कीजिए 4 एक्स माइनस 5 बाय प्लस 16 बराबर0 2 एक्स प्लस वाई माइनस 6 बराबर 0​

Answer 1

Answer:

X = 1and y = 4

Step-by-step explanation:

= 4x-5y+16=0 ........(i)

= 2x+y-6=0 ......... (ii)

from (ii) y=6-2x .....(iii)

replace the value of y in first (i)

= 4x-5(6-2x)+16=0

= 4x-30+10x+16=0

= 14x-14=0

= X = 14/14

= X = 1

replace the value of X in (iii)

= y = 6-2*1

= y = 4

so X = 1 and y= 4
