The price of 5 citrons and 4 fragrant wood apples is 48 units. The price of 4 citrons and ? fragrant [you omitted how many fragrant apples] wood apples is 42 units. Find the price of a citron and the price of a wood apple,     

 

eq 1:                                                        5C + 4F  =  48  

eq 2:                                                        4C + ?F  =  42   

 

eq 3   Multiply both sides of eq 1 by 4             

eq 4   Multiply both sides of eq 2 by 5  

 

Subtract eq 4 from eq 3 to eliminate C, then solve for F
