Thank you so much!

Ms Sue
Thank you.I didn't know * was multiplication.So, would I explain she is not correct because?I don't know how to answer the why part.I knew they would be different I just don't understand why.

Ms Sue
I'm just making sure that you knew I meant the x was multiplication.I don't understand why the a is not represented with a number.I was thinking that I would have to find what a equals.Thank you for helping me.

This is wrong. You were suppose to use the distributive property. Here, let me show you: -3(2+3x)+x-5 = -6+-9x+ x-5 Then, you combine like-terms: -6-5= -11 and then -9x+x= -8x Thus, your answer should be -11-8x. Hope I helped you a little bit.
