Algebra.Com's Answer #502497 by dreamgirl9999(1)![]() ![]() ![]() You can put this solution on YOUR website! First you replace the x in 2x+2y=45 with 2/3y since x=2/3y. \n" ); document.write( "After doing this you should get 2(2/3y)+2y=45. \n" ); document.write( "Now distribute and you should get 1_1/3y (or 4/3) +2y=45. \n" ); document.write( "After combining the like terms: 3_1/3y=45 \n" ); document.write( "Now do the inverse operations by dividing by 3_1/3 on both sides to get y by itself:: y=13_1/2 \n" ); document.write( "Answers are y=13_1/2 (or 13.5) and x=9 (you get 9 by multiplying 2/3 by 13.5). \n" ); document.write( " |
