Algebra.Com's Answer #244087 by mananth(16946)![]() ![]() You can put this solution on YOUR website! (x+y) + (2x+y) = 90 \n" ); document.write( "3x+2y=90 \n" ); document.write( "you have to make y the subject \n" ); document.write( "add -3x to both sides \n" ); document.write( "3x-3x+2y=90-3x \n" ); document.write( "2y=90-3x \n" ); document.write( "divide by 2 \n" ); document.write( "y=90-3x /2 \n" ); document.write( "y=45-(3/2)x \n" ); document.write( " |
