Question

−30=5(x+1)

what is x?

Answer 1

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

Answer 2

`\\ \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`
