How many pounds of walnuts should he use? Represent the walnuts with x and the almonds with y. transale the word statement in 2 equations. I tried this for about 30 minutes. so far i got x + y = 30 and 55x + 70y = 610. \n" ); document.write( "
Algebra.Com's Answer #351893 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Quantity: x + y = 30 \n" ); document.write( "Value: 55x + 70y = 61*30 \n" ); document.write( "----- \n" ); document.write( "Multiply thru Quantity by 55 to get: \n" ); document.write( "55x + 55y = 55*30 \n" ); document.write( "55x + 70y = 61*30 \n" ); document.write( "----- \n" ); document.write( "Subtract and solve for \"y\": \n" ); document.write( "15y = 6*30 \n" ); document.write( "y = 12 lbs. (amt of 55 cent walnuts needed) \n" ); document.write( "--- \n" ); document.write( "Solve for \"x\": \n" ); document.write( "x + y = 30 \n" ); document.write( "y = 18 lbs.
