Question

What is the ordered pair solution?
x+y=6
x=y +2

Answer 1

p(4 , 2)

Explanation:

x + y = 6

x = y +2

we clear the and in both functions

x + y = 6 x = y +2

y = -x + 6 y = x -2

Then we match what is the same and in both functions

x -2 = -x + 6

x + x = 6 + 2

2x = 8

x = 8/2

x = 4

Finally we replace the value obtained from x in any of the 2 functions and give us the value of y

x + y = 6

4 + y = 6

y = 6 - 4

y = 2

p(4 , 2)
