yg jawab pinter banget:)
Semoga kalian mau bantu jawab ya:)
Tolong jawab dari nomor 11-19 ya:)
Jawaban:
11. m + 10 = -30 + 3m
10 + 30 = 3m – m
40 = 2m
40/2 = m
20 = m
12. 8m – 30 = 60 + 10m
-30 – 60 = 10m – 8m
-90 = 2m
-90/2 = m
-45 = m
13. 3m + 10 = 15 – 2m
3m + 2m = 15 – 10
5m = 5
m = 5/5
m = 1
14. m + 20 = 10 – m
m + m = 10 – 20
2m = -10
m = -10/2
m = -5
15. 4m + 20 = 12 + 6m
20 – 12 = 6m – 4m
8 = 2m
8/2 = m
4 = m
16. m + 50 = 25 + 2m
50-25 = 2m – m
25 = m
17. m + 30 = -20 + 3m
30 + 20 = 3m – m
50 = 2m
50/2 = m
25 = m
18. -y + 30 = 20 – 2y
30 – 20 = -2y + y
10 = -y
19. -2y – 5 = 10 – 3y
-2y + 3y = 10 + 5
y = 15
Kalau salah maaf ya 🙂
semoga bermanfaat…. ^^
Jawaban:
11. 10
12. – 45
Penjelasan dengan langkah-langkah:
11.
m + 10 = – 30 + 3m
10 + 30 = 3m – m
20 = 2m
10 = m
12.
8m – 30 = 60 + 10m
-30 – 60 = 10m – 8m
-90 = 2m
-45 = m
Bisa kok kerjain sendiri, itu contoh dan cara. Intinya kalau pindah ruas itu ganti posititf negatifnya, tempatin biar m nya itu positif biar gampang. Untuk kebaikan adek sendiri, coba dikerjakan sendiri sisanya
