The first step to solving this equation is combining the like terms.
\n" ); document.write( "If we add 2x to both sides of the equation, we see that:
\n" ); document.write( "-2x-13+2x=8x+7+2x
\n" ); document.write( "-13=10x+7
\n" ); document.write( "Then, we can subtract 7 from both sides:
\n" ); document.write( "-13-7=10x+7-7
\n" ); document.write( "-20=10x
\n" ); document.write( "Finally, we can divide both sides by 10 to isolate the variable:
\n" ); document.write( "-20/10=10x/10
\n" ); document.write( "-2=x
\n" ); document.write( "So, x is equal to -2. \n" ); document.write( "
