Question

if triangle plus circle = 20 and triangle minus circle = 12 then find the value find the value​

Answer 1

Step-by-step explanation:

Triangle + Circle = 20 - i

Triangle - Circle = 12 - ii

Triangle = 12 + Circle

Therefore , By putting value of triangle

( 12 + Circle ) + Circle = 20

2circle = 20-12

2circle = 8

Circle = 4

Triangle = 12 + Circle ,By taking - ii

Triangle = 12+4

Triangle = 16

Answer 2

Let traingle be 'x' and Circle be 'y'.

X+y=20.....(1)

x-y=12

X=12+y....(2)

(2) in (1)

12+2y=20

2y=8

y=4

and x =16
