Algebra.Com's Answer #34400 by math_kid(1)![]() ![]() ![]() You can put this solution on YOUR website! All you have 2 do is plug in 3x for y and then your problem should read 1/2x+ 1/3(3x)=3! So now all you have to do is simplify 1/3 and 3x. You should get x because the 1/3 and the 3 should cancel out. Now your problem should read: 1/2x+ x=3 and then you finish the problem and you should get 3/2x=3 so u multiply 2 on both sides then u divide by 3 on both sides and you should then get x=2 as your final answer. \n" ); document.write( " |
