Algebra.Com's Answer #175014 by JimboP1977(311)![]() ![]() You can put this solution on YOUR website! 1) well you want to get m on the same side first of all.\r \n" ); document.write( "\n" ); document.write( "So I would take 3m away from each side of the equation. REMEMBER FOR EQUATIONS PROVIDED YOU DO THE SAME ACTION TO BOTH SIDES IT REMAINS BALANCED LIKE SCALES\r \n" ); document.write( "\n" ); document.write( "1/2+(4m-3m)=(3m-3m)-5/2 \n" ); document.write( "1/2+m=-5/2\r \n" ); document.write( "\n" ); document.write( "Take 1/2 from both sides. We have the same denominator (the lower numbers on the fraction) so we can concentrate on the numerators (top numbers)\r \n" ); document.write( "\n" ); document.write( "(1/2-1/2)+m=-5/2-1/2\r \n" ); document.write( "\n" ); document.write( "m= -6/2 (-5-1 = -6)\r \n" ); document.write( "\n" ); document.write( "m= -3\r \n" ); document.write( "\n" ); document.write( "Check answer by subsituting back in.\r \n" ); document.write( "\n" ); document.write( "gives us -11.5 on both sides.\r \n" ); document.write( "\n" ); document.write( "Check through and see if you can follow my working.\r \n" ); document.write( "\n" ); document.write( "Then have a go at 2) on your own and see what you come up with. \n" ); document.write( " |
