Sagot :

-5 because there it can’t be positive and you can reduce the equation
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.
