Best ResponseYou've already chosen the best response.0Do you know what identits and contradictions are in mathematic terms?

Best ResponseYou've already chosen the best response.0An identity is when the equation is true, such as 3 = 1 + 2. A contradiction is when the equation is not true, such as 3 = 4 x 1. If you simplify the equations given, you should be able to solve whether or not they are identities or contradictions

Best ResponseYou've already chosen the best response.01. 5X  20 = 2(3X  10) If we simplify the second half, we will be able to solve the problem. The only step we need to do with this one is distribute, so we just multiply that which is in the parenthesis by the number outside, in this case 2. 1. 5x  20 = 6x  20 is the simplified version for the first problem

Best ResponseYou've already chosen the best response.0As we can see, 5x  20 does not equal 6x  20, so that would be a contradiction

Best ResponseYou've already chosen the best response.02. 4X  16  2X = 2(X8) 4x and 2x are like terms, so we can combine them together to create 2x. 2. 2x  16 = 2(x  8) when we use the distributive property, we can simplify the second half to 2. 2x  16 = 2x  16 So is this an identity or a contradiction

Best ResponseYou've already chosen the best response.03. 6X  15 = 3(2x  6) this is just a one step distributive, so the second half will be 6x  15 = 6x  18 Identity or contradiction? 4. 5X 3(X 4) = 2(X  6) This one is more complicated, as there are parentheses on both sides. We just need to tackle them one at a time. The first half will come out as 5x  3x  12, and then we can combine the like terms (5x and 3x) so that the first half will be 2x  12 The second half is just distribution, so 2x  12. The equation ends up simplifying to 2x  12 = 2x  12 Identity or contradiction? Hope I helped!
