Answer:
x = -1
Step-by-step explanation:
6x + 14 = 7 - x
Add x to each side
6x+x + 14 = 7 - x+x
7x+14 = 7
Subtract 14 from each side
7x+14-14 = 7-14
7x = -7
7x/7 = -7/7
x = -1

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
