Algebra.Com's Answer #591001 by rm29924(97)![]() ![]() You can put this solution on YOUR website! let x = a number \n" ); document.write( "the sum of a number and 4 is \n" ); document.write( "x + 4 \n" ); document.write( "multiplied by 3 is \n" ); document.write( "3(x + 4) \n" ); document.write( "the result is the same as 5 times the number which is 5x decreased by 10 \n" ); document.write( "5x-10 \n" ); document.write( "so our equation is 3(x + 4)=5x-10 \n" ); document.write( "distribute the 3 by multiplying \n" ); document.write( "3x + 12 = 5x - 10 \n" ); document.write( "get the variable x on one side by subtracting 3x from both sides \n" ); document.write( "12 = 2x - 10 \n" ); document.write( "add 10 to both sides \n" ); document.write( "22 = 2x \n" ); document.write( "divide both sides by 2 \n" ); document.write( "x = 11 \n" ); document.write( "answer: the number is 11 \n" ); document.write( " |
