it is -5.
solution:
remove parenthesis, so 12k + 3 x k + 11 = 8k - 7.
combine like terms, so 15k + 33 = 8x - 7
move the terms, so 15k - 8k + 33 = -7
combine like terms again. 7x = 7 - 33
lastly, divide by both 7 to both sides. which is 7x = -40, and that gives -5.
hope this helps, please mark me branliest.
