#y=13#

#2x# in this equation is the same as saying #2# times #x#, so where there is #an# #x#, you put a #5# there.

So you get this

#y = 2(5)+10#

Then

#10+3=13#

So

#y=13#

#y=13# when #x=5#.

#y=2x+3#

#y=2(5)+3#

#y=10+3#

#y=13#

#13#

#y=2x+3#

Plugging in for #x=5#, we get

#y=2*5+3#

#y=10+3#

#y=13#
