--Percent means out of 100, so 20% = 20/100
The prob in other words is asking
  --  $60 is 20% of what number?
'$60'   --          --->  60
'is'       --          --->  =
20%    --         ---> 20/100
'of'     --            ---> * (multiply)
'what number'  ---> x  (variable)

<span>-3x + 2y = 2  eq (1)
 
7x - 3y = 7    eq (2) 
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1) 
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)
Answer: option B. (4,7)
