Matematika SMA Kelas X

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

x - 2 + x + 3 = 3
2x + 1 = 3
2x = 3 - 1
x = 2/2
x = 1

|1 - 2| + |1 + 3| = 3
| - 1 | + | 4 | = 3
1 + 4 = 3 (tidak memenuhi)

x - 2 + x + 3 = -3
2x + 1 = -3
2x = -3 - 1
x = -4/2
x = -2

|-2 - 2| + |-2 + 3| = 3
| - 4 | + | 1 | = 3
4 + 1 = 3 (tidak memenuhi)

HP = {  }

| ×-2 | + | ×+3 | = 3
x-2+x+3 =3
2x = 3-1
2x =2
x= 1
disubsitusikan ke
| ×-2 | + | ×+3 | = 3
