1: multiple both sides by 2
Ex:-7n+10=-32
2: subtract 10 from both sides
Ex: -7n=-42
3:divide both sides by -7 to get n alone
Ex: n=6
Answer is 6 and the process is elimination!
Step-by-step explanation:
here is fig 15
x=36 (v.o.a are equal)
36+y=180
y=180-36=144
y=z=144 vertically

Therefore, the slope of the line is 1/3. In case if you want the equation too.

Therefore, the equation is y=1/3x+2/3
The fromula of a slope:

We have the points
and 
Substitute:

<h3>Answer: slope is undefined.</h3><h3 />
It's a vertical line:
