2. 4 masks and 1 pack of gloves costs $18. Three packs of gloves and 4 masks costs $22. What is the cost of one pack of gloves and one mask?

One mask=$4

One pack of glove=$2

Step-by-step explanation:

Let mask=m

Let glove=g

4m+g=18 (1)

4m+3g=22 (2)

From (1)

g=18-4m

Substitute g=18-4m into equation (2)

4m+3g=22

4m+3 (18-4m) = 22

4m+54-12m=22

4m-12m=22-54

-8m=-32

Divide both sides by - 8

m=4

Substitute m=4 into equation (1)

4m+g=18

4 (4) + g=18

16+g=18

g=18-16

g=2

One mask=$4

One pack of glove=$2
