Is this a positive, negative or netrual veiwpoint? when luke first got his balance band bracelet i was skeptical, but now i am convinced that they really work! luke played his best game ever last night, and he was wearing his balance band bracelet.

positive viewpoint

Explanation:

While at first the viewpoint starts out neutral, it turns positive, favoring the idea of the Balance Band bracelet, rather than opposing it.

hope this helps !!

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
