Answer:
x = 4; y = 2
Step-by-step explanation:
(1) 3x + 2y = 16
(2) 2x – 2y = 4 Add (1) and (2)
5x = 20 Divide each side by 5
(3) x = 4 Substitute (3) into (2)
2×4 – 2y = 4
8 - 2y = 4 Subtract 16 from each side
-2y = -4 Divide each side by -2
y = 2
<em>Check:
</em>
(1) 3×4 + 2×2 = 16
12 + 4 = 16
16 = 16
(2) 2×4 – 2×2 = 4
8 - 4 = 4
4 = 4

Step-by-step explanation:
Any angle of measure 180° or less is supplementary to some angle. A supplementary angle is one that is the difference between 180° and the angle you have. That is, two supplementary angles total 180°.
__
Supplementary angles are readily identifiable in a number of geometries. Adjacent angles of a parallelogram are supplementary; linear angles are supplementary. Same-side interior angles where a transversal crosses parallel lines are supplementary.
