hasil persamaan dari[2x-3]=5 adalah

|2x - 3| = 5

2x - 3 = 5
2x = 5 + 3
2x = 8
x = 8/2
x = 4

2x - 3 = -5
2x = -5 + 3
2x = -2
x = -2/2
x = -1

Hp = {-1, 4}

[ 2x-3]=5 =>>>>

2x - 3 = 5..............2x - 3 = -5
2x = 8....................2x = -2
x = 4.......................x = -1

Hp = { x1, x2 } = { -1, 4 }
