1.	3x-y=6and2x-y=-1solve by substitution metheod
Answer» GIVEN equations $3x-y=6\\\implies -y=6-3x\\\implies y = 3x-6$ $2x-y=-1$ SUBSTITUTING the VALUE of y, we GET, $\implies 2x-(3x-6)=-1\\\implies 2x-3x+6=0\\\implies -<klux>X</klux>+6=0\\\implies -x=-6\\\implies x= 6$ Substituting the value of x, we get, $y = 3(6)-6\\\implies y = 18-6\\\implies y = 12$ $\boxed{\boxed{\bold{Therefore, \ the \ values \ of \ x \ and \ y \ are \ 6 \ and \ 12 \ respectively}}}}}}}}}}$

GIVEN equations

$3x-y=6\\\implies -y=6-3x\\\implies y = 3x-6$
