Question

solve the system of equations , out in ordered pair ..
6x+5y=61
-5x+5y=-5

Answer 1

*Put

Answer 2

Multiply everything in the second equation by -1 to get 5x - 5y = 5

So we now have the system


6x+5y=61
5x - 5y = 5


which adds to

6x+5y=61
5x - 5y = 5
-----------
11x+0y = 66

or just

11x = 66

See where to go from here?

Answer 3

Put it in ordered pairs .. so X=6 how do i solve for y ?

Answer 4

If x = 6, then...

6x+5y=61

6*6+5y=61

36 + 5y = 61

Now solve for y

36 + 5y = 61

5y = 61-36

5y = 25

y = 25/5

y = 5


Note: you can use either equation to find y
