Answer:

x = -7

Explanation:

-30 = 5 (x -1 )

5 ( x + 1 ) =-30

5 (x + 1 ) = - 30

5 5

x + 1 = -6

x + 1 -1 = -6 -1

x = - 7

\\ \rm\Rrightarrow -30=5(x+1)


\\ \rm\Rrightarrow -30=5x+5


\\ \rm\Rrightarrow 5x=-30-5


\\ \rm\Rrightarrow 5x=-35


\\ \rm\Rrightarrow x=(-35)/(-5)


\\ \rm\Rrightarrow x=7
