    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
