Best ResponseYou've already chosen the best response.1The want you to prove the statement using "proof by contradiction" Start with the statement \[ 2(10x+3) \ne 5 (4x3) \] Proof by Contradiction: Assume the statement is false, and that \[ 2(10x+3) = 5 (4x3) \] now distribute the 2 on the left side and distribute the 5 on the right side 20x + 6= 20x15 add 20x to both sides what do you get ?

Best ResponseYou've already chosen the best response.0Well since you add 20x to each side it zeros out both 20x making it 6=15?

Best ResponseYou've already chosen the best response.1yes. and 6 does not equal 15. this is a contradiction. Therefore the assumption we started with that 2(10x+3)=5(4x−3) is not true, and therefore it must be \[ 2(10x+3) \ne5(4x−3)\] and we have proved the statement by contradiction
