K is equal to 2.
You have to move the 4 to the other side and change the addition sign to subtraction. After that, you have to subtract 8 and 4 which will give you 4 and 4 divided by 2 is 2 which means that k equals 2.
Hi!
Its me again
what you do is you move all the numbers on one side of the equal sign and the variable on the other side, when you move the numbers the switch signs
so it will be -2k=4-8
-2k=-4
switch the signs
2k=-4
k=-2
