Question

Решите уравнение. 1) 14х +27х =656 2) 81у - 38у = 645 3) 49z - z = 384 4) 102к - 4к = 1960

Answer 1

1) 41х = 656
х = 656 : 41
х = 16
2) 43у = 645
у = 645 : 43
у = 15
3) 48z = 384
z = 384 : 48
z = 8
4) 98к = 1960 
к = 1960 : 98
к = 20

Answer 2

1. 41х=656
    х=656/41
    х=16
2. 43у=645
    у=645/43
    у=15
3. 48z=384
     z=384/48
     z=8
4.  98к=1960
     к=1960/98
     к=20

Answer 3

1) 14x + 27x = 656 41x = 656 x = 656 / 41 x = 16

2) 81y - 38y = 645 43y = 645 y = 645 / 43 y = 15

3) 49z - z = 384 48z = 384 z = 384 / 48 z = 8

4) 102k - 4k = 1960 98k = 1960 k = 1960 / 98 k = 20

Итак, решения уравнений: 1) x = 16 2) y = 15 3) z = 8 4) k = 20
