Algebra.Com's Answer #7254 by elima(1433)![]() ![]() ![]() You can put this solution on YOUR website! The sum of 38 and twice a number is 124. Find the number. \n" ); document.write( "Sum means the answer to an addition problem. \n" ); document.write( "Let x = the number, twice the number means it is being multiplied by 2. \n" ); document.write( "So we have; \n" ); document.write( "38+2x=124 \n" ); document.write( "We subtract both sides by 38; \n" ); document.write( "38+2x-38=124-38 \n" ); document.write( "2x=86 \n" ); document.write( "Now we divide both sides by 2; \n" ); document.write( " \n" ); document.write( "x=43 \n" ); document.write( "Always check your answer! \n" ); document.write( "38+2(43)=124 \n" ); document.write( "124=124 \n" ); document.write( "Hope you understand! \n" ); document.write( "=) \n" ); document.write( " |
