Algebra.Com's Answer #34397 by music974(43)![]() ![]() ![]() You can put this solution on YOUR website! Well first do 1/2x+1/3(3x)=3.You do this because we know y=3x. Now simplify to get 1/2x+1x=3. Now find a common denominator and add 1/2x+2/2x to get 3/2x=3. Now multiply each side by 2/3 to get x=2. Now plug this into your other equation y=3x to get y=3(2), y=6. So x=2 and y=6. Hope this helps!! \n" ); document.write( " |
