Answer 1

Răspuns:

Explicație pas cu pas:

3.

N + 2N = 15/2

3N = 15/2

N = 15/2 : 3 = 15/2 *1/3 = 5/2

__________

4.

N + 3N = 32/5

4N = 32/5

N = 32/5 : 4 = 32/5 * 1/4 = 8/5

______________

5.

2N + 3/2 = 12/5

2N = 12/5 - 3/2 = 24/10 - 15/10 = 9/10

N = 9/10 : 2 = 9/10 *1/2 = 9/20

______________

6.

3N - 33/16 = 3/8 = 6/16

3N = 33/16 + 6/16 = 39/16

N = 39/16 : 3 = 39/16 * 1/3 = 13/16
