2c + b = 37 ....multiply by -3
4c + 3b = 81
------------------
-6c - 3b = - 111 (result of multiplying by -3)
4c + 3b = 81
------------------add
-2c = - 30
c = -30/-2
c = 15 <== $ 15 for a can of paint
and it costs $ 7 for each brush
1 mile=1258 foot
1 foot=12 inches
63360 is the correct answer
<u>Solution-</u>
The equation given here,
But, at x=1, 
becomes infinity so it can't be a solution to the equation.
∴ x=1 is the extraneous solution of the equation
