Shawn has some nickels in a jar
Let x be the number of nickels in the jar
he put 174 nickels in the jar
Number of nickel added = 174
there are 435 nickels in the jar
Total number of nickel in jar = 435
So, Total number of nickel in jar = intial number of nickel in jar + number of nickels added
435 = x + 174
x = 435 - 174
x = 261
There are 261 nickels in the jar.
