1 + 1 = ?

6r + 8 = 25r - 30
r = ?​

1.)

1 + 1 = 2.

2.)

6r + 8 = 25r - 30

= 6r - 25r = -30 - 8

• = -38

= -19 = -38

[tex] \frac{ - 38}{ - 19} = 2[/tex]

Jadi, nilai r adalah 2

⏩ Penyelesaian soal:

Diketahui:

• 1 + 1
• 6r + 8 = 25r - 30

Ditanya:

• Hasil
• Nilai r

Jawab:

= 1 + 1

= 2

6r + 8 = 25r - 30

6r - 25r = -30 - 8

6r - 25r = -38

-19r = -38

r = -38 ÷ ( -19 )

r = 2
