Answer:
x = 35
Step-by-step explanation:
To solve this problem, we are going to use the concept of angle on a straight line. 
The sum of angle on a straight line is 180°; so if we add the two given angles together, we must arrive at this value. 
 Given angles are: (3x + 2)° and (2x + 3)° 
 3x + 2 + 2x + 3 = 180 
 5x + 5 = 180
 5x = 180-5 
 5x = 175 
 x = 35
