anonymous · Answer

It would be (-1,2) 
I pluged it into the equation
2=2(-1)+4
2=-2+4
2=2

anonymous · Answer

And 
y=x+3
2=-1+3
2=2

If you want an algebraic way, by substitution, put in what y equals into the second equation:
$$ x+3=2x+4\
x-2x=4-3\
-x=1\
x=-1$$
Then plug in this x value into say the 1st equation:
$$ y=(-1)+3\
y=2$$
