3x-13=8 find the value of x-4
1 answer:
3x - 13 = 8
<em><u>Add 13 to both sides.</u></em>
3x = 21
<em><u>Divide both sides by 3.</u></em>
x = 7
Now that we have the value of x we can solve x - 4.
7 - 4 = 3
The value of x is 7, and the answer to the second expression is 3.

Hi!
Put in the values for x and y.
(3 · 3 - 12)-(12 · 3 · 6 - 10)

-209
The answer is -209
Hope this helps! :)
