Answer: The answer to the equation is : x= 4 (Friend me)

Step-by-step explanation: This is a two-step equation. Therefore, you have two steps lol. The first step is combining like terms. So, the simplified equation would be 2x=8. Then the last step would be dividing. You'd divide 2x by 2 and 8 by 2, which would give you x=4!

Answer:

So 3x = x +8 is your equation

We adjust the equation to isolate the x and we end up with 2x = 8

We have to isolate the x even more to turn it into x = 4.

So our final answer is x = 4

Answer:

not

Step-by-step explanation:

$\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] *\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right]=$

First is A and Second is B

Let's find A*B

$\left[\begin{array}{ccc}-2(-2)+4*3&-2*1+4*7\\1(-2)+3*3&1*1+3*7\end{array}\right] =\left[\begin{array}{ccc}16&26\\7&22\end{array}\right]$

$\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right] \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] =$

Now let's find B*A

$\left[\begin{array}{ccc}-2(-2)+1*1&-2*4+1*3\\3(-2)+7*1&3*4+7*3\end{array}\right] =\left[\begin{array}{ccc}5&-5\\1&23\end{array}\right]$
