Question

Un berikut ini.
6. 2x – 5 = 7 – x
7. 4- 3x = 10 – x
8. 2(x + 1) + 3 = 20 – x
9. 3(x - 2) + 5 = x + 7
10. 2(x – 3) + 7 = 3(x + 4) – 9​

Answer 1

Jawaban:

6. 4

7. 7

8.

9.

10.

Penjelasan dengan langkah-langkah:

6. 2x – 5 = 7 – x

2x + x = 7 + 5

3x = 12

= 12/3

= 4

7. 4 – 3x = 10 – x

4 – (–10) = 3x – x

4 + 10 = 3x – x

14 = 2x

= 14/2

= 7

8. 2(x + 1) + 3 = 20 – x

2x + 2 + 3 = 20 – x

2x + 5 = 20 – x

2x + 1 = 20 – 5

3x = 15

x = 5

Maaf ya hanya segitu kk mo blajar buat bsk semoga bisa jadi refrensi dan membantu
