x=5y-3 and x+y=9 as an ordered pair

Question

what is x=5y-3 and x+y=9 as an ordered pair

 

 

Answer 1

Hi Lorrin,

 

First step is to set up your equations in a like manner, then eliminate one equation.

 

x-5y=-3

 x+y=9   [I chose to convert the first equation by multiplying by -1]

-x+5y=3  [Add the two equations together]

    6y=12  [Solve for y]

 

y=2

 

Now, substitute the value of y into the second equation.  x+2=9, therefore x=7.

 

The ordered pair for your answer is (7,2)
