Question

-10÷(?+1).6=30 what is the answer

Answer 1

- 10 / (x + 1 )6 = 30

-10 / 6x +6 = 30

-10 / 2 (3x + 3) = 30

-5 (3x +3 ) = 30

3x +3 = -30 /5

3x +3 = -6

3x = -6 -3

3x = -9

x = -3

hope it helps
thank you !

Answer 2

-10÷(x+1)×6=30
$\frac{ - 10}{(x + 1) \times 6 } = 30$
$\frac{ - 10}{6x + 6} = 30$

$\frac{ - 10}{6(x + 1)} = 30$
$\frac{ - 5}{3(x + 1)} = 30$
$- 5 = 30 \times 3x + 3$
$- 5 = 33 \times 3x$
$3x \times 30 = - 5$
$3x = \frac{ - 5}{30}$
$3x = 6$
$x = 6 - 3$
$x = 3$
