Step-by-step explanation:

Make 8 into a fraction so both k/6 and 8 can be added so it will be 8/1 multiply denominator and munerator by 6 Inorder that denominators of both numbers we are adding is the same (k/6+48/6)since denominators are same it can be considered as one unit thus (k+48/6)move the six to the other side of the equation Inorder that division becomes inverse (multiplication) (6*5=30)

In equation form:k+48=30 move the forty eight to the other side Inorder that plus forty eight becomes negative forty eight k=30-48 therefore k=-18

the real answer is prolly the first anser have a good dayy
