Algebra.Com's Answer #293207 by Mr. Math Wiz(7) ![]() You can put this solution on YOUR website! -First you have to get rid of one varible and the easiest would be x \n" ); document.write( "-To get rid of a variable there has to be a positve number, and then a negative number added together lik -8+8 \n" ); document.write( "4x+5y=2 \n" ); document.write( "8x+10y=4 \n" ); document.write( "-Multiple all of the numbers of the top equation by -2 \n" ); document.write( "-2(4x),-2(5y),-2(2) \n" ); document.write( "-It equals -8x+-10y=-4 \n" ); document.write( "-After adding the equations together by using elimination it equals 0 so the answer is there is no solution \n" ); document.write( "-The answer is C, hope this helped :) \n" ); document.write( " |
