Algebra.Com's Answer #688001 by addingup(3677)![]() ![]() You can put this solution on YOUR website! tulips: t \n" ); document.write( "crocus: c \n" ); document.write( "-------------------------- \n" ); document.write( "6t+10c = 144 multiply all times -2 and add to the next equation \n" ); document.write( "12t+5c = 153 \n" ); document.write( "----------------------------- \n" ); document.write( "12t+5c = 153 \n" ); document.write( "+ \n" ); document.write( "-12t-20c = -288 \n" ); document.write( "--------------- \n" ); document.write( "0t-15c = -135 \n" ); document.write( "-15c = -135 \n" ); document.write( "c = 9 So now we have the cost of the crocus. Now take one of the equations and solve for t: \n" ); document.write( "6t+10(9) = 144 \n" ); document.write( "6t+90 = 144 \n" ); document.write( "6t = 54 \n" ); document.write( "t = 9 \n" ); document.write( "So there you have it. Tulips and crocus are both 9 per pack of bulbs. \n" ); document.write( "-------------------------------------------------- \n" ); document.write( "Check: \n" ); document.write( "6t+10c = 144; 6(9)+10(9) = 144; 54+90 = 144 Correct \n" ); document.write( "12t+5c = 153; 12(9)+5(9) = 153; 108+45 = 153 Also correct \n" ); document.write( ": \n" ); document.write( "John \n" ); document.write( " |
