Question

In 3x+4y=7,why we take x=1 and y=1

Answer 1

Hii mate.......



We tak x = 1 and y = 1 bcoz it makes lhs and rhs equal.... and this is the solution of the equation..



3( 1 ) + 4 ( 1 ) = 7


Hope it helps you mate✌️✌️✌️✌️✌️✌️✌️

Answer 2

According to question,

x = 1 & y = 1

we know LHS = RHS

= so, 3x + 4y = 7

= 3(1) + 4(1) = 7

= 3 + 4 = 7

= 7 = 7 PROVED.
