Algebra.Com's Answer #266512 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! Step 1: 7x+35=3x-24 .... this step is correct. Many students make a mistake distributing.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2: 4x+35= -24 .... Two steps are done here, but it's still correct.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3: 4x=11 ... When 35 is subtracted from both sides, the right side should be equal to -59 (since -24-35=-59). The student forgot that 35 was negative and said that 35-24=11). So this is where the mistake was made.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 4: x=7 .... and this is incorrect because step 3 is incorrect.
