Algebra.Com's Answer #625123 by addingup(3677)![]() ![]() You can put this solution on YOUR website! 2x-3y=16 where x=3y+11, so let's substitute in the equation: \n" ); document.write( "2(3y+11)-3y= 16 \n" ); document.write( "6y+22-3y= 16 Simplify y on left and subtract 22 from both sides: \n" ); document.write( "3y= -6 Divide both sides by 3 \n" ); document.write( "y= -2 Let's plug it in the equation and find x: \n" ); document.write( "------------------------------------- \n" ); document.write( "2x-3(-2)= 16 \n" ); document.write( "2x+6= 16 \n" ); document.write( "2x= 10 \n" ); document.write( "x= 5 \n" ); document.write( "------------------------------- \n" ); document.write( "So there you have it: \n" ); document.write( "y= -2 \n" ); document.write( "x= 5 \n" ); document.write( " |
