Solve this linear equation by elimination method.
Add equation 1 and 2
-----------------------------
Put y value in equation 2
,
Let's say the sides are "a" first one, "b" second one and "c" the third one
ok, let's say the shortest is "a"
and let's say "b" is -> "<span> twice the length of the shortest side"
so b = 2a
and let's say "c" is -> "</span><span>3rd side 14 more feet than length of shortest side"
so c = a + 14
we know the perimeter ( sum of all sides ) is 154
