DENIUS [597]

Answer:

Y=total cost of purchasing the pencils

Step-by-step explanation:

Y=total cost of purchasing the pencils

3.5=price of each pencil

X= number of pencils bought

2.99= shipping cost

There are two approaches to solving the equation -3x + 10 = 4x - 20
pashok25 [27]

Answer:

X =30/7

Step-by-step explanation:

The first way would be something like:

-7x + 10 = -20. The first thing we would do is to subtract 10 from both sides.

Therefore,

-7x+10-10=-20-10

Simplified, we get

-7x=-30

Remove the negative symbols

7x =30

x=30/7

Second example:

10=7x - 20

Add 20 to both sides.

10+20=7x-20+20

Simplified,

30=7x

x = 30/7
