Answer:

The coordinate pair is (5,4)

Explanation:

2x - y = 6 and y = 4.

Find where the two lines intersect

We know the y coordinate is 4. We need to find the x coordinate

Using the first equation, let y =4 and solve for x

2x-y =6

2x-4 = 6

Add 4 to each side

2x-4+4 = 6+4

2x = 10

Divide by 2

2x/2 = 10/2

x =5

The coordinate pair is (5,4)
