With these two problems, I am very confused, because math is not my thing, and I do not understand it.

1. -3[5+2(-7+x)+x]= -3x- (x+3) I do not even know where to begin with this one.

2. 4x+4/5= 5x-1/2-x/3 (the / are over signs) I need to find the product of this problem:(2x-5)^2. Thank you for your help!!
