Answer:
let the heart be x
let the circle be y
so since * is 20, and we have 2 stars equal to 2 circles,
so, according to the first balance,
2(20) + x = 2(y)
40 + x = 2y --------------------------- let it be equation 1
so, according to the second balance,
3(y) = 2(x) + 2(20)
3y = 2x + 40 ------------------------ let it be equation 2
lets take the value of x from equation 1 and substitute x with that in eq. 2
x = 2y - 40
now, substituting x in eq, 2
3y = 2(2y - 40) + 40
3y = 4y - 80 + 40
3y = 4y - 40
40 = y
substituting the value of y in the equation we made of x
x = 2y - 40
x = 2(40) - 40
x = 40
So, the value of heart = 40
the value of star = 40
