Answer:
x=7/10
Explanation:
Because this is a square, we know that all of the sides are equal.
Thus, we know that 6x-1=4x+6.
We can further use Algebra and subtract by 4x on both sides.
Now, we have 10x-1=6.
Then, we can add 1 to both sides, and get 10x=7.
Lastly, let's divide both sides by 10 to isolate x, getting x=7/10, or x=0.7
