how about his one

7+ 5x = 10x2? im not sure I know its
1, but im not sure how.
7 + 5x = 10x  2
Since we need to get the unknowns on one side and the knowns on the other side and change their signs:
5x  10x = 7  2
5x = 5
x = 1
wait how did you what number did you subtract or add from where? to get that? to get 5x10x=72?
is this right??
7=5x=10x2
7+5X10X=10X10X2
7+5=2
7+75X=2+7
5X=5 X=1
Except for typing = instead of + after the 7 in the first line,
and
7+5=2 instead of 7 5x = 2 in the third line,
the rest is OK.
You got the right answer but the intermediate steps contain errors that may just be sloppy typing

i was wondering if anyone could help me on this problem. expand: x^2 (y^2 + 10x) z^3 (5x + 3z^4) First one: x^2 (y^2 + 10x) x^2 is the same thing as 1/x^2. Therefore, we have this: 1/x^2 (y^2 + 10x) Multiply using the distributive …

Thanks Reiny, but I'm still lost. I understand how you multipled by 10X on the right to get 17x, but you went too fast on the left, and I have no idea how you got 10x^220 from the starting left side. Can you show each step?
