Answer:

15 years

Step-by-step explanation:

Let x be the number of years

Tim's salary can be expressed as

[tex]12000+1200x[/tex]

while Tom's salary can be express as

[tex]15000+1000x[/tex]

If their salaries are equal the equation will be

[tex]12000+1200x=15000+1000x[/tex]

Solve for x

[tex]1200x-1000x=15000-12000[/tex]

[tex]200x=3000[/tex]

[tex]x=15[/tex] → Ans
