Materi persamaan nilai mutlak MTK kls 10|2x-3|= |9-x| +3 sertakan caranya y kak​

➢Penyelesaian :

Nilai positif

|2x-3|= |9-x| +3

2x-3 = 9-x + 3

2x = 9-x + 3 + 3

2x = 9-x + 6

2x = 9 + 6 – x

2x = 15 – x

2x+x = 15

3x = 15

x = 15/3

x = 5

Nilai negatif

|2x-3|= |9-x| +3

(2x + x – 3 – 9) = -3

3x -12 = – 3

3x = -3 + 12

3x = 9

x = 9/3

x = 3

Hp { x = 3 atau x = 5 }
