Answered by Rhits

There is some mistake in the equations. They cant be solved. Check the question properly.

volve3657: solve this: 8x + 5y = 9, 3x + 2y = 4

Rhits: x = -2 , y = 5

volve3657: procedure

Rhits: multiply 1st equation by 3 and second by 2. Then subtract the equations obtained and u will get y. Put the value of y in first equation and u will get x

Rhits: Sorry second by 8

volve3657: ok

$\bold\pink{2x + 3y = 8}$

$\bold\purple{4x + 6y = 7}$

${\fbox{\red{Multiply \: by \: 4}}}$

$\bold\blue{4x + 6y = 16}$

${\fbox{LHS \: of \: i \: and \: ii \: are \: same \: but \: RHS\: is \: different}}$
