SOLUTION: on page 58 of the textbook. the problem is a=180-(a-2/n) solve for n. this is what i got so far up to point where i am stuck. a=180(1-2/n) distribute a=180-360/n

: on page 58 of the textbook. the problem is a=180-(a-2/n) solve for n.
this is what i got so far up to point where i am stuck.
a=180(1-2/n) distribute
a=180-360/n +360/n
360/n=180-a -a
?
am i doing this right so far? Also im not sure of the next step. After i got to this point i didnt know what to do This question is from textbook intermediate algebra

So the equation is a=180%281-2%2Fn%29 ?


a=180%281-2%2Fn%29 Start with the given equation.


%28a%29%2F%28180%29=1-2%2Fn Divide both sides by 180.


%28a%29%2F%28180%29-1=-2%2Fn Subtract 1 from both sides.


%28a-180%29%2F%28180%29=-2%2Fn Combine the fractions.


%28n%28a-180%29%29%2F%28180%29=-2 Multiply both sides by "n".


n%28a-180%29=-2%28180%29 Multiply both sides by 180.


n%28a-180%29=-360 Multiply


n=-360%2F%28a-180%29 Divide both sides by a-180.
