Answer 1

Jawab:

1. 9a-8

2. 2a-x+2

3. 30a

4. (2a/3) - 2

5. 5b -3

Penjelasan dengan langkah-langkah:

1. 3a - 7 + 6a - 1 = 3a + 6a -7 -1 = 9a -8

2. (2a-4) + (-x+6) = 2a -4 - x + 6 = 2a -x + 2

3. (-6) x (-5a) = 30a

4. ( 2a - 6) : 3 = (2a/3) - (6/3) = (2a/3) - 2

5. ( 20b - 12) : 4 = (20b/4) - (12/4) = 5b - 3
