Question

−30=5(x+1)

what is x?

Answer 1

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

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

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

$\\ \rm\Rrightarrow 5x=-35$

$\\ \rm\Rrightarrow x=\dfrac{-35}{-5}$

$\\ \rm\Rrightarrow x=7$

Answer 2

Answer:

x = -7

Step-by-step 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
