document.write( "Question 218470: Please explain multi step equations to me because i dont understand it at all. I am in the 7th grade in advanced math and i am doing pre algebra. Also when you are doing a multi step equation and you have an subtraction sign do you change it and then change the sign of the next number? EX. 4p+5-7p=-1 would i change the subtraction sign between the 5 and the 7 to an addition sign and then change the positive 7 to a negative 7? My teacher told us that but that makes me more confused! HELP! \n" ); document.write( "

1/6(y+42)-15=-3
\n" ); document.write( "y/6+42/6-15=3
\n" ); document.write( "y/6+7-15=3
\n" ); document.write( "y/6=3-7+15
\n" ); document.write( "y/6=11
\n" ); document.write( "y=66 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "1/6(66+42)-15=3
\n" ); document.write( "1/6*108-15=3
\n" ); document.write( "108/6-15=3
\n" ); document.write( "18-15=3
\n" ); document.write( "3=3
\n" ); document.write( "------------------------------------------
\n" ); document.write( "4p+5-7p=-1 before changing signs try to combine like terms.
\n" ); document.write( "4p-7p+5=-1
\n" ); document.write( "-3p+5=-1 now subtract 5 from both sides
\n" ); document.write( "-3p+5-5=-1-5
\n" ); document.write( "-3p=-6 divide both sides by -3
\n" ); document.write( "-3p/-3=-6/-3
\n" ); document.write( "p=2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "4*2+5-7*2=-1
\n" ); document.write( "8+5-14=-1
\n" ); document.write( "13-14=-1
\n" ); document.write( "-1=-1 \n" ); document.write( "
