tentukan HP

a.) 3x -6 = 9
b.) 3x+5 = 11
c.) 4x +2 = 2x -11​

Answer 1

Jawaban:

A.) x = 5

B.) x = 2

C.) x = -6½

Penjelasan dengan langkah-langkah:

A.) 3x - 6 = 9

3x = 9 + 6

3x = 15

x = 15 : 3

x = 5

B.) 3x + 5 = 11

3x = 11 - 5

3x = 6

x = 6 : 3

x = 2

C.) 4x + 2 = 2x - 11

4x - 2x = -11 - 2

2x = -13

x = -13 : 2

x = -6½

Maaf kalo salah :v
