Jika 7² + y = 50Tentukan:☞ Nilai y☞ 2y + 5​

Penjelasan dengan langkah-langkah:

7² + y = 50

___

  • Nilai y

7² + y = 50

(7 × 7) + y = 50

49 + y = 50

y = 50 – 49

y = 1

  • Nilai 2y + 5

2(1) + 5

= 2 + 5

= 7

Jika 7² + y = 50

Tentukan :

• nilai y

• 2y + 5

Penyelesaian :

7² + y = 50

(7 × 7) + y = 50

49 + y = 50

y = 50 – 49

y = 1

2y + 5

= 2(1) + 5

= (2 × 1) + 5

= 2 + 5

= 7
