-47 + 6k = 3k - 2Add 47 to each side:6k = 3k +45Subtract 3k from each side:3k = 45Divide each side by 3:k = 15
3k+16 = 5k subtract 3k from both sides 16 = 2k divide both sides by 2 8 = k
3k + 3 = 8 3k = 8 -3 3k = 5 k = 5/3
Assuming that the problem looks like this: (12/jk)(3k/4)Multiplying fractions is much easier than adding them. When adding, we need to make sure they both have a common denominator. But With multiplication, we can just multiply the numerator by the numerator and the denominator by the denominator.So we get (12/jk)(3k/4)=(36k)/(4jk)Now we just need to simplify. We can divide by 4 and cancel a k, giving us 9/j.
3k can mean 3,000 as k is a symbol for 1,000. If you're running a race, 3k can also mean 3 kilometers or 3,000 meters.
-47 + 6k = 3k - 2Add 47 to each side:6k = 3k +45Subtract 3k from each side:3k = 45Divide each side by 3:k = 15
( 12/jk ) x ( 3k/4 ) = 9/j
3k+16 = 5k subtract 3k from both sides 16 = 2k divide both sides by 2 8 = k
3k..
A 3K is 1.86 miles
3k + 3 = 8 3k = 8 -3 3k = 5 k = 5/3
"3k" is shorthand for 3,000.
(3k - 2)(3k - 2) or (3k - 2)2
-47 + 6k = 3k - 2Add 47 to each side:6k = 3k +45Subtract 3k from each side:3k = 45Divide each side by 3:k = 15
==> 3k+14=k ==>3k-k=-14 ==>2k=-14 ==>k=-7 ans...

3k is a quick way of saying three thousand.
