(Show Source): You have the right to put this solution on her website! The problem asks girlfriend to find two unknown numbers. So let"s start by calling one number x andthe other number y..The trouble tells you the if you include the 2 numbers, the amount is 17. In equation kind thiscan be composed as:.x + y = 17 .The problem then tells you that the second number (call it y) is 2 much more than twice the othernumber. That method it equals 2 an ext than 2x. For this reason in equation kind you have the right to write:.y = 2x + 2 .Return to equation 1. If girlfriend subtract x from both sides of this equation you change thatequation come y = 17 - x. Since we now understand that y amounts to 17 - x we can replace y by 17 - xin equation 2 to get:.17 - x = 2x + 2.Let"s collect the x terms on the left side of this equation and also the number on the ideal side of the equation. Start by gaining rid the the 17 ~ above the left side by subtracting 17 indigenous both political parties to get:.-x = 2x -15.Then eliminate the 2x on the appropriate side by subtracting 2x indigenous both political parties to get:.-3x = -15.Now you deserve to solve because that x by separating both political parties of this equation by -3. As soon as you do thatdivision the result is:.x = -15/-3 = 5.So among the numbers is 5. And also since the two numbers complete 17, the various other number must be 17 - 5 = 12. .As a rapid check, girlfriend can double the smaller number and include 2.
