#x=2 and y=1#

#y=3x-5#------- Let this be equation (1)

# 6x+3y=15# ---------- Let this be equation(2)

Substituting value of #y# from(1) in (2),

#=>6x+3(3x-5)=15#

#=> 6x + 9x -15 =15#

#=> 15x = 15+14 =30#

#=> x= 30/15 =2#

#therefore x=2#

Now substitute this value of #x# in equation(1):

#=> y = 3xx(2) - 5#

#=> y = 6-5 =1#

#therefore y=1#

#x=2 and y=1#
