Let the two parts be x (the first part) and y (the second part).
x+y=24 and
7x+5y=146 makes your system of linear equations
We can combine them, subtracting 5 times the first equation from the second equation:
--> -->
Then we substitute the value found for x into the first equation to find y:
--> -->
