Answer:

x = 38

Step-by-step explanation:

  • Intersection is occupied by x
  • remaining part of set A = 149 - x
  • remaining part of set B = 160 - x

Now,

  • (149 - x) + (x) + (160 - x) + (2x + 3) = 350

  • 149 - x + x + 160 - x + 2x + 3 = 350

  • 312 + x = 350

  • x = 350 - 312

  • x = 38
