document.write( "Question 831056: In problems like (-31xm) + -2 =618 why do you bring the -2 over first? I can't figure out why sometimes it is the parenthesis and sometimes just the number. I thought it was order or operations but this doesn't seem to apply, it is not the parenthesis or the times part. It is the adding/subtracting you do first. How do you know???? \n" ); document.write( "

You can put this solution on YOUR website!
Your given equation has three terms:
\n" ); document.write( "-31xm;
\n" ); document.write( "-2;
\n" ); document.write( "618.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The grouping symbols around -31xm emphasise the grouped factors as a separate number from other numbers and symbols in the equation. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The variable term is -31xm. A person may want to solve for one or other of the variables contained in this term. Objective is to isolate the variable term, and finally one of the variables.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The left member contains -2.
\n" ); document.write( "We maintain equality between left and right members if we ADD THE ADDITIVE INVERSE OF -2 TO BOTH THE LEFT AND RIGHT MEMBERS.
\n" ); document.write( "-31xm+(-2)+2=618+2 ----- removing parentheses from -31xm causes no trouble; putting parentheses around -2 both emphasises that number and on this site will help with rendering.
\n" ); document.write( "-
\n" ); document.write( "-31xm+0=618+2 ----- Property and meaning of ADDITIVE INVERSE.
\n" ); document.write( "
\n" );
