4th number line.

Step-by-step explanation:

The other 3 number lines don't make sense.

#1: The dot is between 10 and 15, and -18 is less than 15, so incorrect.

#3: The dot is between -15 and -10, and -18 is lesser, so incorrect.

#2: The dot is between 10 and 15, and -18 is negative, so incorrect.

∴ #4 number line is correct

Hi Meep21,

3(7x - 9) - 19x = - 15
21x - 27 - 19x = - 15
2x = 27 - 15
2x = 12
x = 12 / 2
x = 6

S = {6}

x + 3(x - 7) = 19
x + 3x - 21 = 19
4x = 19 + 21
4x = 40
x = 40 / 4
x = 10

S= {10}
