Step-by-step explanation:
To do this, we will substitute the x values to their corresponding equations,
1)

Given 2x + 15 = 19
Calculated 2x + 15 = 19
Given = Calculated, this solution is correct.
2)

Given 3 + x + 2 - x = 16
Calculated 3 + x + 2 - x = 5
Given not equal to calculated, this solution is incorrect.
3)

Given (x+2)/5 = 2
Calculated (x+2)/5 = 2
Given = Calculated, this solution is correct.
4)


Given 2x - 8 = 6
Calculated 2x - 8 = 6
Given = Calculated, this solution is correct.
5)


Given 1/3x + 5 = 14
Calculated 1/3x + 5 = 11
Given not equal to Calculated, this solution is not correct.
Therefore the Correct solutions are 1,3 and 4.

Answer:
109
Step-by-step explanation:
Given : Dividend = 8439
Divisor = 245
Solution:
Dividend =( Divisor *Quotient )+Remainder
8439 = (245*34)+Remainder
8439 =8330+Remainder
8439 -8330 = Remainder
109 = Remainder
Thus The remainder of 8439÷245 is 109
