Question

if 2, star + 1 circle=34.03 kg 1 star + 3 circle = 39590 g Then, 3 star + 2 circle = ?

Answer 1

let star be s & circle be c then;
2s + 1c = 34.03

(1s + 3c = 39.59) ×2
2s + 6c = 79.18
2s + 1c = 34.03

0 + 7c = 113.21
c = 113.21/7
= 16.17
similarly. s = 0.65

3s + 2c = 3×0.65 + 2×16.17
= 1.95+ 32.34
= 34.29
therefore 3 star + 2 circle = 34.29 kg
