The first step to solving your equation would be to subtract 6.4 from both sides.

Subtract 6.4 from 42.5 so you can get 3.5n by itself.
42.5-6.4=36.1
then since you now have 3.5n by itself you are goin to divide 36.1 by 3.5
36.1/3.5=10.31
so n=10.31

The sum of two numbers is 22. The difference is 6. What are the two numbers?

algol [13]

Answer:

Numbers are 14 and 8

Step-by-step explanation:

Let the 2 numbers be x and y.

Write 2 equations:

x + y = 22

x - y = 6

Solve by substitution:

x - y = 6

x = y + 6

Plug into the other equation:

(y + 6) + y = 22

2y + 6 = 22

2y = 16

y = 8

Plug into either equation:

x + 8 = 22

x = 14

Numbers are 14 and 8

She can only buy 2 whole packs.

Acording to the graph, 2 whole pakcs will cost $22, and 3 whole packs will cost $33. She can't afford 3 whole packs as we can see as she only has $30.50.

Let me know if you have any questions, thanks!
