Question

X+y=11 ;2x-3y=7 solve the following equation

Answer 1

Given equation

$x+y=11--(1)\\2x-3y=7--(2)$

Multiplying the first equation by 2, we get,

$2x+2y=22--(3)$

Solving (2) and (3), we get,

$2x-3y=7\\\underline{2x+2y=22}\\\underline{\underline{-5y=-15}}\\\implies y = 3$

Substituting y = 3 in the first equation, we get,

$x+3=11\\\implies x = 11-3\\\implies x =8$

$\boxed{\boxed{\bold{Therefore, \ the \ values \ of \ x \ and \ y \ are \ 8 \ and \ 3 \ respectively}}}}}}$
