The most important thing to remember here is PEMDAS. Its the order of equations acronym.\r
\n" ); document.write( "\n" ); document.write( "PEMDAS
\n" ); document.write( "P: parentheses
\n" ); document.write( "E: exponents
\n" ); document.write( "M: multiplication
\n" ); document.write( "D: division
\n" ); document.write( "A: addition
\n" ); document.write( "S: subtraction\r
\n" ); document.write( "\n" ); document.write( "If you start solving the equation in that order, you'll be fine. Here's how you do it. \r
\n" ); document.write( "\n" ); document.write( "m+3(m-4)=16
\n" ); document.write( "Now you distribute the 3 throughout the parentheses(P). Multiply both things inside the parentheses by the number on the outside.
\n" ); document.write( "m+(3m-12)=16
\n" ); document.write( "You don't need the parentheses anymore since you've finished distributing.
\n" ); document.write( "m+3m-12=16
\n" ); document.write( "Since you have two \"m\" variables in your equation, you can combine them. Just add them together.
\n" ); document.write( "4m-12=16
\n" ); document.write( "You can now add that \"-12\" to the other side. You want to isolate the variable, the letter, on one side, so you can solve for it.
\n" ); document.write( "4m-12=16
\n" ); document.write( " +12 +12
\n" ); document.write( "4m=28
\n" ); document.write( "Now you divide both sides by the number next to the variable, to get rid of it.
\n" ); document.write( "4m=28
\n" ); document.write( "÷4 ÷4
\n" ); document.write( "And there's your answer.
\n" ); document.write( "m=7
\n" ); document.write( "
\n" );
