<PRE><B>Question 148920</B>
d=# dimes
q=# quarters
coefficient=value of coin in cents


10d+25q=695
d+q=35


Solve for d in the second equation:
d=35-q


Plug that into the first equation:
10(35-q)+25q=695


Distribute:
350-10q+25q=695


Combine like terms:
350+15q=695


Subtract 350 from both sides
15q=345


Divide by 15
q=23


Plug that into the second equation:
d+23=35
d=12


23 quarters
