<span>3x+5y=2 (1)
9x+11y=14 (2)

multiply equation (1) by 3
9x + 15y = 6

</span>9x + 15y = 6 (1')
9x + 11y =14 (2)
-------------------------subtract
4y = -8
 y = -2

3x+5y =2
3x+5(-2) =2
3x - 10 = 2
3x = 12
x = 4

How many different triangles can be constructed with three sides, each measuring 5 centimeters?
Akimi4 [234]
The first thing we will do is define an equilateral triangle:
 In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °
 Every equilateral triangle consists of three equal sides and three congruent angles.
 Therefore, there can be a triangle with three equal sides (5 centimeters in this case).
