Answer:
1. Many possible solutions, two solutions would be: (-1,0) and (1,0)
2. x = −
2
± i
Step-by-step explanation:
For the first equation, since its linear, there are many possible solutions!
two solutions would be: (-1,0) and (1,0)
For the second one, replace y with 0 and solve
x = −2 ± <em>i</em>

<em> -Aadi x</em>
7x + 5x = 180
12x = 180
x = 15
Therefore, the 2 angles equal (7*15) and (5*15) which equals
105 degrees and 75 degrees
