Question

A system of equations is shown below: 3x − y = 2 x + y = 6 The x-coordinate of the solution to this system of equations is . (4 points)

Answer 1

The x coordinate is 2

Explanation:

3x − y = 2

x + y = 6

Add the two equations together to eliminate y

3x − y = 2

x + y = 6

-------------------

4x + 0y = 8

Divide by 4

4x/4 = 8/4

x = 2

The x coordinate is 2
