Answer:
- 8n + 9
Step-by-step explanation:
A - B
= - 3n + 2 - (5n - 7) ← distribute by - 1
= - 3n + 2 - 5n + 7 ← collect like terms
= - 8n + 9 → or 9 - 8n
Soni can put 24 pencils can be put into each box with four pencils remaining.
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The best way to find this out is to find the total number, minus the remained.
In this case,
196 - 4 = 192.
As We have got to put the pencils into 8 boxes, we have to divide 192 by 8,
192 / 8 = 24.
Also, If x represents the number of pencils per box, the equation
8x + 4 = 196.
Therefore, Soni can put 24 pencils can be put into each box with four pencils remaining.
