B-3a=2 3B- 6a=12 solve algebraicly show steps
lora16 [44]
B - 3A = 2
3B - 6A = 12

(2)B - (6)A =4
3B - 6A = 12

Subtract

-B = -8
B = 8

Plugin 8 for B

8 - 3A = 2
8 = 3A + 2
6 = 3A
2 = A

(Double checking)
3(8) - 6A = 12
-6A = 12-24 = -12
- 6A = -12
Divide by -6
A= 2
It works

A = 2. B = 8. Hope this helps

Which mathematical sentence most accurately expresses the information in the problem below? Crystal has 121 compact discs that s
ExtremeBDS [4]

Crystal has 121 compact discs. The total number of boxes required are 5.

<u>Solution:</u>

Given, Crystal has 121 compact discs that she wants to put into boxes.  

Each of the boxes that she brought home holds 25 discs.  

We have to find how many of these boxes will she need for all of her discs?

Now, we know that, number of boxes required =\frac{\text {total number of discs}}{\text {capacity of one box}}=\frac{121}{25}=4.84=5

Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.  

Hence, the total number of boxes required are 5.
