HabisinPoin2990 + 188 + n = 12n – 3n = jgn follow biar telat ｡◕‿◕｡

1) 2990 + 188 + n = 12n – 3

________________________

2990 + 188 + n = 12n – 3

(2.990 + 188) + n = 12n – 3

3.178 + n = 12n – 3

n = 12n – 3 – 3.178

n = 12n – 3.181

n = 12n – 3.181 – 12n

-11n = -3.181

n = (-3.181)/-11

n = 3.181/11

Penjelasan dengan langkah-langkah:

2990 + 188 + n = 12n – 3

3178 + n = 12n – 3

n – 12n = – 3 – 3178

– 11n = – 3181

n = – 3181/-11

n = 3181/11
