Carilah nilai m , n dan q dari :
• 5m + 20 = 3m – 20
• 8 + 5q = 4 – 4q
• 1/2n – 3 = 5n + 2
selamat mengerjakan!!
Jangan ngasal.. :v
Quiz!! [+50]
Penjelasan dengan langkah-langkah:
• 5m + 20 = 3m – 20
5m – 3m = -20 – 20
2m = -40
m = -20
• 8 + 5q = 4 – 4q
5q + 4q = 4 – 8
9q = -4
q = -4/9
• 1/2n – 3 = 5n + 2
1/2n – 5n = 2 + 3
-9/2n = 5
n = 5 ÷ (-9/2)
n = -10/9

Penjelasan dengan langkah-langkah:
• 5m + 20 = 3m – 20
5m – 3m = -20 – 20
2m = – 40
m = -40/2
m = – 20
• 8 + 5q = 4 – 4q
5q + 4q = 4 – 8
9q = -4
q = -4/9
• ½n – 3 = 5n + 2
5n – ½n = -3 – 2
10/2 n – ½n = -5
9/2 n = -5
n = -5 x 2/9
n = –10/9
