Find the value of ?

Let, Circle be 'x'

Star be 'y'

Triangle be 'z'

As per the fourth equation: 4x = 32

Therefore: x= 32/4 or x= 8

As per the first equation: 2x + 2z = 30

or, 2(8) + 2z = 30

or, 16 + 2z = 30

or, 2z = 30 -16

0r, 2z = 14

z = 7

As per the third equation: 2x + y+ z = 29

or, 16 + y + 7 = 29

or, y + 23 = 29

or, y = 6

Hence x=8, y=6 and z=7
