5x – 12 = 13

8(x + 3) = 64

using algebra

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

        +12    +12 (add 12 to the 13)

    5x=25  

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64  (first use distributive property)

   8x+24=64

        -24   -24    (then subtract 24 to 64 which is 40)

    8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D

stop using my information please it isn’t me i can get in a lot of trouble.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
