1. 2/5 = 5/10n + 2
You can start by simplifying 5/10 to 1/2
So you will have:
2/5 = 1/2n + 2
Now you can subtract 2 from both sides to get
2/5 - 2 = 1/2n
Simplify the numbers
-8/5 = 1/2n
Now, multiply both sides by 2
n = -16/5
2. 7/10 = 3/8k + 1
First, subtract 1 from both sides
7/10 -1 = 3/8k
-3/10 = 3/8k
Now multiply both sides by 8/3
(-3/10)(8/3) = k
k = -8/10
k = -4/5

1.) subtract 2 from both sides then divide both sides by 5/10. That's how you get in. You do the same process in #2.
