Question

3×4200 (T-60)=2×4200×(30-T)
Beserta caranya

Answer 1

Verified answer

3 × 4200 × (T-60) = 2 × 4200 × (30-T)
3 (T-60) × 4200 = 2 (30-T) × 4200
3 (T-60) = 2 (30-T)
3T - 180 = 60 - 2T
3T + 2T = 60 + 180
5T = 240
T = 240/5
T = 48

Answer 2

3×4200 (T-60)=2×4200×(30-T)
karena ni perkalian, dan 4200 di kedua sisi sama-sama ada jadi boleh dielimimasi, sehingga menghasilkan persamaan
3 × (T-60)=2 x (30-T)
3T - 180 = 60 - 2T
5T = 240
T = 240/5
T = 48
