Yes
Explanation:
Substituting
- in
#-2color(red)(x)+3color(blue)(y)#
#color(white)("XXX")# gives#-2(color(red)(2))+3(color(blue)(3)) =-4+9 = 5#
#color(white)("XXX")# So the given coordinates are a solution to the first equation. - in
#3color(red)(x)+2color(y)=12#
#color(white)("XXX")# gives#3(color(red)(2))+2(color(blue)(3))=6+6 =12#
#color(white)("XXX")# So the given coordinates are a solution to the second equation.
Since the given coordinates are a solution to both equations,
they are a solution to the system of equations.
