Question

49z-z=384, 102k-4k=1960.

Answer 1

49z-z=384
48z=384
z=384:48
z=8

102k-4k-1960
98k = 1960
k= 1960:98
k=20

Answer 2

1. 49z-z=384
    48z=384
     z=384:48
     z=8.   Проверка   49*8-8=384
                                 392-8=384
                                   384=384.
2. 102k-4k=1960
     98k=1960
      k=1960:98
      k=20.    Проверка   102*20-4*20=1960
                                    2040-80=1960
                                      1960=1960. 

Answer 3

To solve the equations, let's simplify them step by step:

1. 49z - z = 384

Simplifying the left side of the equation, we have:

48z = 384

Now, we isolate z by dividing both sides of the equation by 48:

48z/48 = 384/48

z = 8

Therefore, the solution for the first equation is z = 8.

2. 102k - 4k = 1960

Simplifying the left side of the equation, we have:

98k = 1960

Now, we isolate k by dividing both sides of the equation by 98:

98k/98 = 1960/98

k = 20

Therefore, the solution for the second equation is k = 20.

In summary, the solutions for the given equations are z = 8 and k = 20.
