tolong bantu 2(2n-1)-4-(n+3)= 48, tentukan nilai n yg memnuhi 2(p-1)-3+(2p+3)=38, tentukan nilai p yg memenuhi

2(2n - 1) - 4 - (n + 3) = 48
=> 4n - 2 - 4 - n - 3 = 48
=> 3n - 9 = 48
=> 3n = 48 + 9
=> 3n = 57
=> n = 57/3
=> n = 19

2(p - 1) - 3 + (2p + 3) = 38
=> 2p - 2 - 3 + 2p + 3 = 38
=> 4p - 2 = 38
=> 4p = 38 + 2
=> 4p = 40
=> p = 40/4
=> p = 10

jawabannya ada di gambar ya jawabannya udah aku cek juga insyaallah bener
