The number "k" is 25
Solution:
Given that, Six less then a number, k, is 19
To find: write and solve an equation to solve for k
From given information,
Let the number is "k"
Six less then a number k is 19
Here, "less" means reduced or subtracted
6 is subtracted from k
This statement means that, number "k" reduced by 6 is equal to 18
k - 6 = 19
k = 19 + 6
k = 25
Thus the number "k" is 25
