The standard form of a line is in the form
![Ax + By = C](https://tex.z-dn.net/?f=Ax%20%2B%20By%20%3D%20C)
A, B and C are integers, and A is positive. Let's start with multiplying the whole equation by 3 to get rid of denominators:
![3y+6=x](https://tex.z-dn.net/?f=3y%2B6%3Dx)
Subtract 3y from both sides:
![6=x-3y](https://tex.z-dn.net/?f=6%3Dx-3y)
Which of course is equivalent to
![x-3y=6](https://tex.z-dn.net/?f=x-3y%3D6)
Which is the standard form, given the coefficients A=1, B=-3, C=6.
70+68= 138
138 is the answer because by the triangle sum theorem says all the inside angles of a triangle equal 180 degrees and a straight line is 180 degrees so to find x you just must add up the other two sides of the triangle

N=New emily's savings 2.N-55=x
Answer:
80 degrees i believe
Step-by-step explanation:
if supplementary angles =180 then 180-100=80
