x + 3(x + 2) = 3(x + 4) + 31
⇒ x + 3x + 6 = 3x + 12 + 31
⇒ 4x + 6 = 3x + 43
⇒ 4x - 3x = 43 - 6
⇒ x = 37

Answer:
x + 3(x+2) = 3(x+4) + 31
x + 3x + 6 = 3(x+4) + 31
4x + 6 = 3(x+4) + 31
4x + 6 = 3x + 12 + 31
4x + 6 = 3x + 43
4x + 6-6 = 3x + 43-6
4x = 3x + 37
4x - 3x = 3x + 37 - 3x
1x = 37
x= 37/1
x= 37
