Select all the equations that describe the situation.



Group of answer choices

z - 135 - 450

z + 135 = 450

z = 450 + 135

z = 450 - 135

Answer 1

Note that:

• Han's house = 450 m from school
• Lin's house = (450 - 135) from school

Looking at the options, we can tell that the letter "z" represents Lin.

• => z = (450 - 135)
• => z = 450 - 135

This option matches with Option D.

Option D is correct.
