Question

What is this i can't solve

Answer 1

x=27, y= 21

Explanation:

We can writ proportions to solve this. Red side over blue side

8 14 18

---------- = ------------- = -------------

12 y x

Using cross products on the first two

8y = 12*14

8y = 168

Divide by 8

8y/8 = 168/8

y =21

Now we can use cross products on the second and third

14x = 18y

We know y

14x = 18*21

14x =378

Divide by 14

14x/14 =378/14

x =27
