Question

Su perímetro es 14cm y el triple de su lado menor es igual al doble de su lado mayor

Answer 1

4y + 2x = 14

3y = 2x - > y = 2x/3

4y + 2x = 14

4 ( 2x/3 ) + 2x = 14

8x/3 + 2x = 14

8x + 6x = 42

14x = 42

x = 42/14

x = 3

4y + 2x = 14

4y + 2 . 3 = 14

4y + 6 = 14

4y = 14 - 6

4y = 8

y = 8/4

y = 2

4y + 2x = 14

4.2 + 2 . 3 = 14

8 + 6 = 14

14 = 14
