Answer 1

✯✯ QUESTION ✯✯

Find the value of k if x=2 , y=1 is a solution of equation 2x+3y=k...

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Value\:of\:x=2}$

$\longmapsto\tt{Value\:of\:y=1}$

$\longmapsto\tt{Value\:of\:k=?}$

➥Now ,

$\longmapsto\tt{2x+3y=k}$

$\longmapsto\tt{2(2)+3(1)=k}$

$\longmapsto\tt{4+3=k}$

$\longmapsto\tt{\large{\boxed{\bold{\bold{\pink{\sf{k=7}}}}}}}$

☛So , The value of k is 7....
