-1 times the second equation =
=
--4
Now we are given that replace the third equation by the sum of itself and -1 times the second equation
So, New third equation = 
= 
Hence the new third equation is 
Answer:
45°
Step-by-step explanation:
Angles in a triangle add to 180 degrees, so
- 2x - 12 + 2x + 17 + 9x - 7 = 180
- 13x - 2 = 180
- 13x = 182
- x = 14
So, the measure of angle X is 2(14)+17=45°
