You can put this solution on YOUR website!
given:
(1) c+=+2a+-+5
(2) c+=+a+%2B+45
Subtract (2) from (1)
0+=+a+-+50
a+=+50
From (1):
c+=+2%2A50+-+5
c+=+95
Angela's score is 50, and Carolina's is 95
check:
(1) c+=+2a+-+5
95+=+2%2A50+-+5
95+=+95
(2) c+=+a+%2B+45%7D%7D%0D%0A%7B%7B%7B95+=+50+%2B+45
95+=+95
OK
