Answer:

x = 7.5

Step-by-step explanation:

So the equation looks like this:

2X -3 =12

So we are first going to get rid of -3 by adding 3 to both sides of the equal sign:

2X -3 = 12

    + 3   +3

SO the equation looks like this now:

2x = 15

Now we are going to segregate the variable x by dividing 2x and 15 by 2:

2x/2 = 15/2

x = 7.5

So in order to check our work we are going to substitute 7.5 where the x variable is in the equation:

2X -3 =12 or 2(7.5) - 3 = 12

2(7.5) - 3 = 12

15 - 3 = 12

12 = 12

So our answer to what the variable x equals is 7.5.

I hope this helps you!!

Answer:

B. 4.5c + 4 = 24

Step-by-step explanation:

T = cx + py  is the equation you are given.

T = 24 because it is the total amount of money you can spend.

x = 4.5 because each phone case costs 4.50 dollars

p = 2 because you bought 2 pop sockets.

y = 2 because each pop socket costs 2 dollars.

There is no c because you don't know the number of phone cases you bought.

Now, we have to substitute the values into the equation:

24 = 4.5x + 2(2)

24 = 4.5x + 4

4.5x + 4 = 24       <--- This is your answer

Hope this helps!
