Tentukan himpunan penyelesaian dari pesamaan berikut.
A. m=13+9
m=21
HP= {21}
b.12-y=15-7y
-y+7y=15-12
6y=3
y=1/2
HP={1/2}
c.6y-9=5y-10
6y-5y=-10+9
y=-1
HP={-1}
d.3p+p=17-5
4p=12
p=3
HP={3}
e.7n-4n=-17-4
3n=-21
n=-7
HP={-7}
A. M = 13 + 9
M = 22
b. 12 – 8y = 15 – 7y
7y – 8y = 15 – 12
-1y = 3
y = -3
c. 6y – 9 = 5y – 10
6y – 5y = 9 – 10
y = -1
d. 3p + p = 17-5
4p = 12
p = 3
e. 7n – 4n = -4 – 17
3n = -21
n = -7
