Question 652669: I am kind of unsure of my response for this equation:
It asks me to rewrite the equation in terms of "w"
A=2(L+W)
This is my work...
A=2(L+W)
A=2L+2W
A-2L=2W
((A-2L)/2)=W --------> I'm not sure if this would be my final answer or could it be (((A/2)-L))=W
Please explain to me why my first solution is right/wrong. Thank you.
