tolong jawabannya ya beserta caranya :) bagian A dan E

Mapel : Matematika
Kelas : X SMA
Bab : Mutlak

Pembahasan :
5|2x - 1| + 4 = 11
5|2x - 1| = 7
|2x - 1| = 7/5
(2x - 1)² = (7/5)²
(2x - 1)² - (7/5)² = 0
(2x - 1 + 7/5)(2x - 1 - 7/5) = 0
(2x + 2/5)(2x - 12/5) = 0
x = -1/5
x = 6/5

Hp : {-1/5 , 6/5}

————————————————
3 - |4x - 5| = -15
|4x - 5| = 3 + 15
|4x - 5| = 18
(4x - 5)² = 18²
(4x - 5)² - 18² = 0
(4x - 5 + 18)(4x - 5 - 18) = 0
(4x + 13)(4x - 23) = 0
x = -13/4
x = 23/4

Hp : {-13/4 , 23/4}
