You can use subtraction to get how many computers the rest of the school has.
The equations that can be used to find the number of computers in the rest of the school is
How to find the number of computers in the rest of the school?Since it is known as there are total 178 computers,
and that Grade 3 has got 58 computers,
Thus, remaining number of computers if we don't count grade 3 is
Grade 4 has 57 out of those 120 computers,
Thus,
Remaining computers in the school (say y computers are left) is
Thus,
The equations that can be used to find the number of computers in the rest of the school is

Step-by-step explanation:
Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.
Then, x= Grade 3 computers +Grade 4 computers.
And y = Total computers - x
Therefore, The equations can be used to find how many computers the rest of the school has.
