$\"+-7%2F5%5Ex%2B7%2F2=3%2F5%5Ex%2B9%2F10+\"$
\n" ); document.write( "Begin by multiplying both sides by 5^x
\n" ); document.write( " $\"+-7%2B%287%2F2%295%5Ex=3%2B%289%2F10%295%5Ex+\"$
\n" ); document.write( "Next, multiply both sides by 10:
\n" ); document.write( " $\"+-70%2B%2835%295%5Ex=30%2B%2827%295%5Ex+\"$
\n" ); document.write( " $\"+-70%2B%288%295%5Ex=30+\"$
\n" ); document.write( " $\"+%288%295%5Ex=100+\"$
\n" ); document.write( " $\"+5%5Ex=100%2F8+\"$
\n" ); document.write( "Take log base 5 of both sides:
\n" ); document.write( " $\"+x=log%285%2C100%2F8%29+\"$
\n" ); document.write( " $\"+x=log%285%2C12.5%29+\"$
\n" ); document.write( " $\"+x=log%2812.5%29%2Flog%285%29+\"$
\n" ); document.write( " $\"+x=1.569+\"$
