Answer»

Given:-

→3x+y+1=0๛(1)

→2x-3y+8=0๛(2)

\rule{200}{1}

To Find:-

The Value of X and y?

\rule{200}{1}

Answer:-

★Using ELIMINATION Method★

•MULTIPLY eq–(1)with 2 and Multiply eq–(2) with 3

→6x+2y+2=0

→6x+2y=-2๛(3)

→6x-9y+24=0

→6x-9y=-24๛(4)

♦Subtracting (3)&(4)♦

→6x+2y=-2

→6x-9y=-24

♠Signs Changed♠

→11y=22

→y=\frac{\cancel{22}}{\cancel{11}}

→y=2๛(5)

๛Using (5) in (1)๛

→3x+2+1=0

→3x+3=0

→3x=-3

→x=\frac{\cancel{-3}}{\cancel{3}}

→x=-1

\rule{200}{1}

★x=-1 and y=2★

\rule{200}{2}
