21n + 7



Combine like terms.

n, 7n, 7n, 3n, and 3n are all like terms. These can be added together as 21n.

7 is the only term by itself.

Put these together to get 21n + 7.

Pavel [41]

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

-x + 0y = -34
x = 34
y = 58 - 34 = 24
