Answer:
We have been given the matrix m as m = [874][205].
We can rewrite this matrix as
\begin{gathered}m=\begin{pmatrix}8 &7&4\\2&0&5 \\\end{pmatrix}\\\end{gathered}m=(827045)
Now, we need to the find m_{12}m12
It means we need to find the entity that is present in the first row and the second column.
From the above matrix, we can see that 7 is in the first row and the second column.
Therefore, we have
m_{12}= 7m12=7
You multiply what’s on top of that
You need to isolate x.
71 - 5x = 9x - 13
Add 13 to both sides.
84 - 5x = 9x
Add 5x to both sides.
84 = 14x
Divide both sides by 14.
6 = x
<h3>The answer is x = 6.</h3>
