Tentukan himpunan penyelesaian dari 1. 15+x= 35 2. 27=y-9. 3.x+5=-4​

1. 15+x= 35

x = 35 – 15

x = 20

2. 27 = y – 9

-y = -9 – 27

-y = -36

y = 36

3. x + 5 = -4

x = -4 – 5

x = -9

Soal:

Tentukan himpunan penyelesaian dari 1. 15+x= 35 2. 27=y-9. 3.x+5=-4​

Jawab:

1.) 15+x= 35

=> 15 + x = 35

=> x = 35 – 15

=> x = 20

HP = {20}

__________

2.) 27 = y – 9

=> 27 – 9 = y

=> 18 = y

=> y = 18

HP = {18}

___________

3.) x + 5 = -4

=> x = -4 – 5

=> x = -9

HP = {-9}
