i'm sorry but i don't know i wish you alot of luck on what you are working on
X - 65 - 4x.
3x - 65.
I assume that you subtract x times four (a number, x, multiplied by 4) FROM the difference of x and 65 (the same number and 65).
Hope this helps!
Answer:
The weight of each circle is 2g
distribute -9 to 2.7 and 1.55
-9x2.7= -24.3
-9x1.55= -13.95
then subtract -13.95 from -24.3
-24.3-(13.95)= -10.35
then add 3 to -10.35
answer= 7.35
