Answer:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

[tex]\frac{x-2}{15}[/tex] = [tex]\frac{x-1}{18}[/tex]

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7
