Huu hapa ni ufumbuzi wa swali la 8: Ili kupata thamani ya usemi, tutabadilisha thamani za x, y, n, na r hatua kwa hatua. Step 1: Badilisha x=5 katika milinganyo ya y, n, na r. y = 2x y = 2(5) y = 10 n = x + 9 n = 5 + 9 n = 14 r = n + 6 r = 14 + 6 r = 20 Step 2: Badilisha thamani za x, y, n, na r katika usemi x + (2n-r)/(y). 5 + (2(14) - 20)/(10) Step 3: Rahisisha usemi. Kwanza, kokotoa nambari ya sehemu: 2(14) - 20 = 28 - 20 = 8 Sasa, badilisha nambari iliyorahisishwa kwenye usemi: 5 + (8)/(10) Rahisisha sehemu (8)/(10) kwa kugawanya nambari na denominator kwa 2: (8)/(10) = (4)/(5) Hivyo, usemi unakuwa: 5 + (4)/(5) Hii inaweza kuandikwa kama nambari mchanganyiko. 5(4)/(5) Thamani ya usemi ni 5(4)/(5). Hii inalingana na chaguo D. Drop the next question.
