Answer:

k = 2

Step-by-step explanation:

To get the variable k alone, you must add (-1) from the left side and add (1) to the right side.

k - 1 = 1

  +1   +1

k = 2

Answer:-
k=2

Solution:
k-1 = 1
k = 1+1
k = 2

∵ Positive sign changes into negative sign as we shift the number/value/variable to the opposite side
