Just write an equation for each statement \n" ); document.write( "; \n" ); document.write( "The sum of two numbers is 2. \n" ); document.write( "a + b = 2 \n" ); document.write( ": \n" ); document.write( "If one number is subtracted from the other, their difference is 8. \n" ); document.write( "a - b = 8 \n" ); document.write( ": \n" ); document.write( "Find the numbers \n" ); document.write( "Use elimination here \n" ); document.write( "a + b = 2 \n" ); document.write( "a - b = 8 \n" ); document.write( "------------adding eliminates b, find a \n" ); document.write( "2a = 10 \n" ); document.write( "a = 5 \n" ); document.write( "Find b using the 1st equation \n" ); document.write( "5 + b = 2 \n" ); document.write( "b = 2 - 5 \n" ); document.write( "b = -3 \n" ); document.write( ": \n" ); document.write( "Check solutions in the 2nd equation \n" ); document.write( "5 - (-3) = minus a minus is a plus as you probably already know \n" ); document.write( "5 + 3 = 8 \n" ); document.write( " |
