AlgSubstitution (check plz)
posted by thomas .
k well i had to use substitution to find the point of intersection for these 2 equations
xy=10
3x+y=11
i chose to substitute y in the first equation
my final answer was (1/2 , 5) can someone clarify this, and if it's wrong, where'd i make a mistake?
In the first equation, y= x10
put that into the second to get
3x + x10=11
4x=21
x= 4.25
Then you can solve for y.
It's right! Congrats!
