Answer
u = -½ is not a solution of 8u - 1 = 6u
Explanation
We are asked to determine if u = -½ is a solution of
8u - 1 = 6u
To know this, we can just solve the equation
8u - 1 = 6u
8u - 6u = 1
2u = 1
Divide both sides by 2
(2u/2) = (1/2)
u = ½
So, u = -½ is evidently not a solution of this equation.
Hope this Helps!!!
