It asks me to Simplify the following expression. 2x − 2y + 3z − 2x − y + 2z = ? A) 4x − 3y + 5z B) −2y − 3y + 5z C) −2x − 3y + 6z D)−3y + 5z How would i do this??
the answer is A
Okay but i just wanna know how i would find A to be the correct answer. What are the steps , the like terms??
cz u do the like terms cz 2x times 2x is 4 and so on>>>
damn where you come from like let a chick have a chance @sarahashley .... but i guess thats right what she said all the like terms or all the ones that have the same letter behind them you combine
2x times 2x is 4x and 2y minus y is -3y and then 3z plus 2z is 5z
Haha :) thank you both so much i am loving all the help, im good a t math but sometimes i suck.
yeah
