(3,_),(_,-1),2x-3y=5 \n" ); document.write( ". \n" ); document.write( "This is two separate problems. The first problem is that you are given (3,_) and the equation \n" ); document.write( ". \n" ); document.write( "2x - 3y = 5 \n" ); document.write( ". \n" ); document.write( "The 3 in (3,___) represents x. Substitute 3 for x in the equation and solve for y: \n" ); document.write( ". \n" ); document.write( "2(3) - 3y = 5 \n" ); document.write( ". \n" ); document.write( "Multiply out the left side to get: \n" ); document.write( ". \n" ); document.write( "6 - 3y = 5 \n" ); document.write( ". \n" ); document.write( "Subtract 6 from both sides: \n" ); document.write( ". \n" ); document.write( "-3y = -1 \n" ); document.write( ". \n" ); document.write( "Divide both sides by -3 to end up with: \n" ); document.write( ". \n" ); document.write( "y = (-1/-3) = 1/3 \n" ); document.write( ". \n" ); document.write( "So the missing entry in (3,_) is 1/3 and the answer becomes (3, 1/3) \n" ); document.write( ". \n" ); document.write( "The second problem involves the answer set (_, -1) for the equation 2x - 3y = 5. Substitute \n" ); document.write( "-1 for y in the equation to get: \n" ); document.write( ". \n" ); document.write( "2x - 3(-1) = 5 \n" ); document.write( ". \n" ); document.write( "And multiply out to get: \n" ); document.write( ". \n" ); document.write( "2x + 3 = 5 \n" ); document.write( ". \n" ); document.write( "Subtract 3 from both sides: \n" ); document.write( ". \n" ); document.write( "2x = 2 \n" ); document.write( ". \n" ); document.write( "Divide both sides by 2 and the result is: \n" ); document.write( ". \n" ); document.write( "x = 1 \n" ); document.write( ". \n" ); document.write( "So the missing x value in (_, -1) is 1 and the answer set is (1, -1) \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand what the problem was looking for. \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
