Answer:
Step-by-step explanation:
We have been given: 102-42
And 33y -11y
We have to write equivalent expression of:
102-42=60
We can consider:
40+20
30+30
80-20
90-30
All the above expressions are equivalent because they have same result as the given expression has.
Now, equivalent expression of:
33y -11y=22y
We can consider:
11y+11y
44y-22y
55y-33y
12y+10y
All the above expressions are equivalent because they have same result as the given expression has.
Hence, the above expressions are the required equivalent expression.
