x:14 = 7:8
x:14 = x/14
7:8 = 7/8
x/14 = 7/8
Multiply the numerator of the 1st ratio with the denominator of the 2nd. 
And multiply the numerator of the 2nd ratio with the denominator of the 1st.
Doing so, we get - 
x * 8 = 7 * 14
So, 8x = 7 * 14
8x = 98
We divide 98 by 8 (transposition method)
x = 98/8
Therefore, x = 12.25
 
        
             
        
        
        
1/3 of 60 to 1/5 of 100 is 20 to 20.
1/3 x 60/1 =20
1/5 x 100/1=20
Reminder: You're able to cross-multiply.

Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10 
x-2y=2
------------
 2x = 12, so x = 6.  Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2.  The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
