Hey there!!
Given equation :
... 3 ( 2k - 9 ) + 4 = 5 - 2 ( k + 7 )
Using the distributive property :
... 6k - 27 + 4 = 5 - 2k - 14
Combining the like terms :
... 6k - 23 = -2k - 9
Adding 2k on both sides :
... 8k - 23 = -9
Adding 23 on both sides :
... 8k = 24
Dividing by 8 on both sides :
... k = 24 / 8
... k = 3
The required answer is 3.
Hope my answer helps!!
