You can put this solution on YOUR website!
40 = (2)(1+g)/ 13.8-g
\n" ); document.write( ":
\n" ); document.write( "I am assuming you mean:
\n" ); document.write( " $\"%282%29%2A%281%2Bg%29%2F13.8+-+g\"$ = 40
\n" ); document.write( ":
\n" ); document.write( " $\"%282%2B2g%29%2F13.8+-+g\"$ = 40; multiplied what's inside the brackets
\n" ); document.write( ":
\n" ); document.write( "2 + 2g - 13.8g = 13.8(40); multiplied eq by 13.8, gets rid of the denominator
\n" ); document.write( ":
\n" ); document.write( "2g - 13.8g = 552 - 2; Subtracted 2 from both sides
\n" ); document.write( ":
\n" ); document.write( "-11.8g = 550; do the math
\n" ); document.write( ":
\n" ); document.write( "g = 550/-11.8; divide both sides by -11.8
\n" ); document.write( ":
\n" ); document.write( "g = -46.61 is the solution
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check in original equation:
\n" ); document.write( " $\"%282%29%2A%281-46.61%29%2F13.8+-+%28-46.61%29\"$ = 40
\n" ); document.write( " $\"%282%29%2A%281-46.61%29%2F13.8+%2B+46.61\"$ = 40; minus a minus is a plus
\n" ); document.write( " $\"%282%29%2A%28-45.61%29%2F13.8+%2B+46.61\"$ = 40;
\n" ); document.write( " $\"%28-91.22%29%2F13.8+%2B+46.61\"$ = 40;
\n" ); document.write( "-6.61 + 46.61 = 40; confirms our solution
\n" ); document.write( ":
