x/0.4=2x + 1.2 ----(1)
\n" ); document.write( "Multiply through out by 0.4
\n" ); document.write( "x=(0.4)X(2x) +(1.2)X(0.4)
\n" ); document.write( "x = (0.8)x+0.48
\n" ); document.write( "Multiplying by 100 through out
\n" ); document.write( "100x = (80.0)x +48.00
\n" ); document.write( "100x-80x = 48
\n" ); document.write( "20x = 48
\n" ); document.write( "x =48/20 = (12X4)/(5X4) = 12/5 (cancelling 4 in the nr and in the dr)
\n" ); document.write( "That is x = 2.4
\n" ); document.write( "Answer: x= 2.4
\n" ); document.write( "Verification: Putting x = 2.4 in (1)
\n" ); document.write( "LHS = x/0.4 = 2.4/0.4 = 24/4 = 6
\n" ); document.write( "RHS = 2x +1.2 = 2X(2.4) +1.2 = 4.8+1.2 =6 = LHS
\n" ); document.write( "Therefore our answer is correct \n" ); document.write( "
\n" );
