\n" ); document.write( "\n" ); document.write( "So far, I applied the LCD method to this. My LCD is 4b which I multiplied to the equation to get 4(5-b) + 3b = 7(4) which equals 20-4b+3b=28. From that point I'm unsure if you do set it to zero or set it as -4b+3b = 28-20 but it doesn't say solve for b. Or if the LCD method is even applied at all. \n" ); document.write( "
