Best ResponseYou've already chosen the best response.0As this is an isosceles trapezoid the line segments AD and BC are equal in length. So I suppose Diagonal to be equal and 5x = 3x+40. A linear equation in one variable.

Best ResponseYou've already chosen the best response.05x and 3x + 40. so 5x = 3x + 40 5x  3x = 40 x = 40/2 x = 20

Best ResponseYou've already chosen the best response.0so 5x = 5*20 = 100 3x + 40 = 3*20 + 40 = 60 + 40 = 100

Best ResponseYou've already chosen the best response.0In this step 5x and 3x + 40. so 5x = 3x + 40 5x  3x = 40 In this step why did they switch the equals sign and how do you know its minus not plus. @Atsie x = 40/2 x = 20

Best ResponseYou've already chosen the best response.2@smartbrain Okay, so they are simply subtracting \(3x\) from both sides. Since they are subtracting, the positive \(3x\) becomes negative. You see? Also, they did not switch the equals sign they subtracted \(3x\) from both sides.

Best ResponseYou've already chosen the best response.0How did they conclude that the 3x is to be subtracted from both sides and not the 5x?

Best ResponseYou've already chosen the best response.2If the \(5x\) is subtracted from both sides, then there will only be ONE side! Because if the \(5x\) was subtracted it would be \(=3x  40  5x\) which simply can't happen.

Best ResponseYou've already chosen the best response.0I see, so you are trying to eliminate the x in the problem? Right?
