Hey there!
So, if

, this would mean that we would do

and from this, we would get 8.
We will then need to find what is

.


=

So, the equation would really look like
. . .
![\left[\begin{array}{ccc} 8*(7)-2*4 = 48 \\ \\ x=\boxed{7}\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%208%2A%287%29-2%2A4%20%3D%2048%20%5C%5C%20%5C%5C%20x%3D%5Cboxed%7B7%7D%5Cend%7Barray%7D%5Cright%5D%20)
Hope this helps.

Answer:
<u>~Senpi boi here~</u>
Step-by-step explanation:
Multiply all terms by x and cancel:
x+2x+1=1x
3x+1=x(Simplify both sides of the equation)
3x+1−x=x−x(Subtract x from both sides)
2x+1=0
2x+1−1=0−1(Subtract 1 from both sides)
2x=−1
2x
2
=
−1
2
(Divide both sides by 2)
x=
−1
2
