You can put this solution on YOUR website!
Just use some basic algebra operations
\n" ); document.write( ":
\n" ); document.write( "9 + 2.7t = -4.8t -6?
\n" ); document.write( "2.7t + 4.8t = -6 - 9
\n" ); document.write( "7.5t = - 15
\n" ); document.write( "t = $\"%28-15%29%2F7.5\"$
\n" ); document.write( "t = -2
\n" ); document.write( "Check solution in original equation, replace t with -2
\n" ); document.write( ":
\n" ); document.write( " $\"1%2F2\"$ (5y+8) = 4y - 5
\n" ); document.write( "Get rid of that fraction, multiply both sides by 2
\n" ); document.write( "5y + 8 = 2(4y - 5)
\n" ); document.write( "5y + 8 = 8y - 10
\n" ); document.write( "5y - 8y = -10 - 8
\n" ); document.write( "-3y = -18
\n" ); document.write( "y has to be positive, multiply both sides by -1
\n" ); document.write( "3y = 18
\n" ); document.write( "y = $\"18%2F3\"$
\n" ); document.write( "y = 6
\n" ); document.write( "Check this solution the same way
\n" ); document.write( " \n" ); document.write( "
