Answer:
-1/2 is not a solution
Step-by-step explanation:
8u-1 = 6u
Subtract 8u from each side
8u-1 -8u = 6u-8u
-1 = -2u
Divide each side by -2
-1 /-2 = -2u/-2
1/2 = u
No, u = - 1/2 is not a solution of 8u - 1 = 6u
[tex]8u - 1 = 6u \\ 8u - 6u = 1 \\ 2u = 1 \\ \\ u = \frac{1}{2} [/tex]
here we get u = +1/2
