x+(x+1)=-11

x + (x + 1) = - 11

x = - 6

Solution steps

x + (x + 1) = - 11

Remove parentheses:

(a) = a

x + x + 1 = - 11

Add similar elements:

x + x = 2 x

2 x + 1 = - 11

Move

1

to the right side

2 x = - 12

Divide both sides by

2

x = - 6

86 = 2 n - 4 (- 4 - 3 n)

- 3 (0) + 6 y = 24

- \frac{7}{3} m + \frac{25}{6} = m - \frac{5}{2}

25 = - 8 + 9 (x + 3)

z = \frac{1 + i}{i} + \frac{i}{i - 1}
