a) x = 6 ==> 10x = 18 ==> x = 18/10
3 10
=============================================
b) 3 = 60 ==> 3x = 420 ==> x = 140
7 x
============================================
c) 6 = 14 ==> 14x = 30 ==. x = 30/14
x 5
===============================================
d) 7 = 42 ==> 7x = 252 ==> x = 36
6 x
================================================
e) 35 = 30 ==> 35.20 = 25.30 ==> 700 = 750 F
25 20
=================================================
f) 22 = 6 ==> 198 = 90 F
15 9
