Algebra.Com's Answer #222793 by Miceandwine(15)![]() ![]() ![]() You can put this solution on YOUR website! Okay, so let's set up this problem: \n" ); document.write( "2x(the perm)+x(the haircut)+5(lunch)=50 \n" ); document.write( "2x+x+5=50 \n" ); document.write( "So the first thing we can do is subtract the 5 from both sides and add the x's \n" ); document.write( "3x+5-5=50-5 \n" ); document.write( "3x=45 Now we can divide the whole problem by 3 to get: \n" ); document.write( "x=15 \n" ); document.write( "Great, now we know how much the haircut cost! Just double that to find out how much the perm costs, $30. Let's check our answer: \n" ); document.write( "$15(haircut)+$30 (perm)+$5(lunch)=$50 (total) \n" ); document.write( "I hope I helped! \n" ); document.write( " |
