Answer:
x = 1
y = 5
Step-by-step explanation:
You can use either substitution or elimination for this problem. I will use substitution.
Step 1: Replace x in the 1st equation
-10(y-4) + 3y = 5
-10y + 40 + 3y = 5
-7y = -35
y = 5
Step 2: Plug <em>y </em>into an original equation to find <em>x</em>
x = 5 - 4
x = 1
And you have your final answers!
Answer: Every polygon that is not a triabgle (3 vertices), quadrilateral (4 vertices) or pentagon (5 vertices) has more than 5 vertices. So it would be a hexagon, heptagon, etc.
