Jawaban :
8 + 4 = 11 (Tidak benar, hasil seharusnya 12, bukan 11).
x - 12 = 20
x = 20 + 12
x = 32
5 - a = 17
a = 5 - 17
a = -12
9y + 3 = 48
9y = 48 - 3
9y = 45
y = 45 / 9
y = 5
12x - 20 = 4
12x = 4 + 20
12x = 24
x = 24 / 12
x = 2
saya bantu 5 nomor, lainnya harus bisa sendiri
semangat :-)
Penjelasan dengan langkah-langkah:
Aku bantu 5 nomor lainnya lagi ya :)
6. -4a+3=16
-4a = 16-3
-4a = 13
a = -13/4
7. m-10 = -5
m= -5+10
m = 5
8. 25+r=1
r= 1-25
r= -24
9. 20n+1=-99
20n = -99-1
20n= -100
n= -100/20
n=-5
10. -12z-4=-41
-12z = -41+4
-12z = -37
z= -37/-12
z= 37/12
dah itu aja kk
