You can put this solution on YOUR website! If the price of kerosene is increased by #6(#-NAIRA) per litre, find the new price per litre if two thirds of the new price is equal to five sevenths of the old price.
-------
Let original price be "x".
New price is "x+6"
----
Equations:
(2/3)(x+6) = (5/7)x
-------
Multiply both sides by 21 to get:
14(x+6) = 15x
x = 14*6
x = #84
x+6 = #90
