2k - 3k - m + 2m = -k + m
It is -57k + 324
When factored it is: (3k+5)(k-1)
-k + 3k = 2k
==> 3k+14=k ==>3k-k=-14 ==>2k=-14 ==>k=-7 ans...
1k/2k, 2k/4k, 3k/6k and so on.
It can be simplified to: 9k
The non zero multiples of a number k are all numbers which can be written as n*k where n is not 0. So ..., -3k, -2k, -1k, 1k, 2k, 3k, ...
-4. -3k+10=k+2.... First we have to move the K to one side -3k+10=k+2 __________ This will reduce -3k to -2k and k+2 to just 2 K -2k+10=2 Now we have to subtract 10 to both sides as to get k alone. -2k+10=2 ________ Now we should have -2k on one side and 2-10 on the other. -10 -2k=2-10....... 2-10= 8. We have to get -2k into just K on itself so we divide by 2. -2k=-8 ______ Your answer is 4. You have to do one side what you do the other. 2
By using algebra.
1k=1ooo 2k=2ooo 3k=3000 .......and so on.......
k=4
