Y=1/4 x+7 y=1/2x+5 the why coordinate of the solution to the system shown is a.9 b.11 1/2 c. 19

For this case we have a system of two equations with two unknowns, represented by x and y respectively.

To solve we follow the steps below:

Step 1:

We multiply the second equation by -1

Step 2:

We add both equations

Step 3:

We clear x:

Step 4:

We substitute "x" in any of the equations and clear "y":

Thus, the solution of the system is given by:

The y coordinate = 9
