X = 3
How?
You have to equal both sides together.
3x + 1 = x + 7
Subtract x from both sides.
2x + 1 = 7
Subtract 1 from both sides.
2x = 6
Divide 2 from both sides.
X = 3

Answer:
{1}
Step-by-step explanation:
We find determinant for the given matrix and set it equal to -1
To find determinant we apply formula


|A| = x^2 - 2x
Now we set the determinant = -1

Add 1 on both sides

Now factor it
(x-1)(x-1) = 0
Set each factor =0 and solve for x
x- 1=0 so x=1
