Question

Tentukan himpunan penyelsaian dari kalimat berikut jika variabel pada himpunan bilangan bulat.
a. x + 8 = 17
b. y : 5 = -12
c. 15 ₋ p = 42
d. 9 × m = 108
e. n + n+ n + n = 52
f. a × a = 81

Answer 1

A.  x + 8 = 17
x = 17 - 8 = 11
b . y : 5 = -12
y = 5 x - 12 = -60
c. 15 - p = 42
15 - 42 = p
-27 = p
d. 9m = 108
m = 108 / 9 = 12
e. n + n + n + n = 52
4 n = 52
n = 13
f. a x a = 81
a² = 8
a = 9  atau a = -9

Answer 2

A. x+8=17
x=17-8=9
b. y:5=12
y=12.5=60
c.15-p=42
-p=42-15
p=-27
d. 9.m=108
m=108:9=12
e.n4=52
n=52:4=13
f.a2=81
a=9
