Answer:
Explanation:
1/2(-3/2n+1)=3/4
distribution first, so, 1/2 times -3/2 then you get -3/4. finishing distribution 1/2 times 1 and you get 1/2.
then your equation becomes -3/4(1/2)=3/4
to get rid of the -3/4 you have to add a positive 3/4. what you do to one side you have to do to the other so you add 3/4 to the other side and get 1 1/2.
then to get rid of the 1/2 you have to add -1/2 to both sides so you do so and end up with a answer of 1
I only know one technique to doing so but there is that sorry ik i wasnt a lot of help but I showed my work.
