Answer:

w=0, z=5

Step-by-step explanation:

Solve the following equations for w and z:

w + 2z = 10

4w + z = 5

We can use elimination.  Multiply the second equation by -2 and eliminate z

w + 2z = 10

-8w  -2z = -10

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

-7w = 0

Therefore w =0

Now we can find z

4w + z = 5

4(0) +z = 5

z=5
