Actually, bot are equal. Because 3 feet make a yard and there 2 yard so 6 feet made 2 yards.
When solving this equation you get x = -3.
To solve this, simply follow the order of operations for solving.
----> start by dividing both sides by 5
-----> Now you can transform the front side of the equation to use negative exponents.

Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.
-3 = x
This is false because
is an irrational number, despite being between 1 and 2.
