Algebra.Com's Answer #232474 by jessica43(140)![]() ![]() ![]() You can put this solution on YOUR website! To solve this problem for x, you want to get x by itself by combining like terms. \n" ); document.write( "First, add 12 to each side of the equation: \n" ); document.write( "2x-8=4x-12 \n" ); document.write( "2x-8+12 = 4x-12+12 \n" ); document.write( "2x+4=4x \n" ); document.write( "Now we want to bring the x variables to the same side. To do this, we are going to subtract 2x from each side: \n" ); document.write( "2x+4 = 4x \n" ); document.write( "2x+4-2x = 4x-2x (to subtract 2x from 4x, just subtract the coefficients: 4x-2x = (4-2)x = 2x) \n" ); document.write( "4 = 2x \n" ); document.write( "Finally, divided each side by 2: \n" ); document.write( "4 = 2x \n" ); document.write( "4/2 = 2x/2 \n" ); document.write( "2=x \n" ); document.write( "So your answer is x=2. \n" ); document.write( " |
