The solution is
#color(blue)(x=1,y=6#

# y=color(blue)(x+5#..........equation #1#
#y=-2x+8#.......equation #2#

Substituting equation #1# in equation #2#

#y=-2x+8#
#color(blue)(x+5) = -2x+8#

#3x=8-5#

#3x=3#

#color(blue)(x=1#

Finding #y# by substituting #x# in equation #1#

# y=x+5#
# y=1+5#

#color(blue)(y=6#
