Let J = the number of computers Julius sold and S = the number of computers Sam sold.
1) J+=+5%2AS "Julius sold 5 times as many computers as Sam sold..."
2) J%2BS+=+78 "In total, they sold 78 computers."
Substitute the J in eqation 1) into equation 2) and solve for S.
3) %285%2AS%29%2BS+=+78
3a) 6S+=+78
3b) S+=+13 so:
J+=+5%2813%29
J+=+65
Julius sold 65 computers.
