Algebra.Com's Answer #310342 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! The easiest way to solve this system is to add the two equations to eliminate x: \n" ); document.write( "-8x + 8x -3y + 7y = 4 \n" ); document.write( "4y = 4 \n" ); document.write( "y = 1 \n" ); document.write( "Now substitute this value for y into either of the two equations. Using equation 1, we have: \n" ); document.write( "-8x - 3(1) = 69 \n" ); document.write( "-8x = 72 \n" ); document.write( "x = -9 \n" ); document.write( "Ans: x = -9, y = 1 \n" ); document.write( "Check: \n" ); document.write( "8(-9) + 7(1) = -65 \n" ); document.write( " |
