Okay, so he started out with 45 lbs. 

Let's make 40% into a decimal.

Identify the solution of the system -2x-4y=1<br> 12y=-6x-3
RoseWind [281]
-2x - 4y = 1
<u>12y</u> = <u>-6x - 3</u>
 12         12
   y = -0.5x - 0.25

-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
<u>     - 1  - 1</u> 
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-2(0) - 4y = 1
0 - 4y = 1
<u>-4y</u> = <u>1</u>
 -4    -4
   y = -0.25
(x, y) = (0,-0.25)
