Answer:

x = 3 and y = - 1

Step-by-step explanation:

1a.  2x + y = 5          Solve for y in the first equation.

           y = -2x + 5

1b.   2(-2x + 5) = 2x - 8

       -4x + 10 = 2x - 8

         -6x + 10 = -8

         -6x = -18

1c.          x = 3

       2y = 2x - 8      

       2y = 2(3) - 8

       2y = 6 - 8

        2y = -2

           y = -1

Check  Use x = 3; y = -1

1d.      2x + y = 5                    2y = 2x - 8

        2(3)  - 1 = 5                   2(-1) = 2(3) - 8

         6 -  1 = 5                      -2 = 6 - 8

            5 = 5                         -2 = -2             Checked

What is the measure of LXZW?<br> 850<br> 150°<br> Y<br> 65°<br> 95<br> Z<br> 215°<br> W<br> 30°
Semenov [28]

Answer:

so the answer is 95°

Step-by-step explanation:

The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
