You may GROUP coins, by placing one penny, one nickel and one dime in each group.
Each group is worth then 1 + 5 + 10 = 16 cents.
Having the total of 160 cents MEANS that you have = 10 such groups.
From this point, there is only one step to get the
ANSWER. 10 pennies, 10 nickels and 10 dimes.
OR
x + 5x + 10x = 160
16x = 160
x = 160/16 = 10,
and you get the same answer.
Solved.
