.

quarters + dimes + nickels + pennies = 19


x        + 3x    + (2x-1)  + (3x+2)  = 19


9x                                   = 19 + 1 - 2 = 18


x                                                 = 18/9 = 2.


ANSWER.  2 quarters,  3*2 = 6 dimes, 2*2-1 = 3 nickels and 3*2+2 = 8 pennies.


CHECK.  Total coins = 2 + 6 + 3 + 8 = 19.   ! Correct !

Solved.
