6=2(d+1)

Solution for 6=2(d+1) equation:

Simplifying
6 = 2(d + 1)

Reorder the terms:
6 = 2(1 + d)
6 = (1 * 2 + d * 2)
6 = (2 + 2d)

Solving
6 = 2 + 2d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-2d' to each side of the equation.
6 + -2d = 2 + 2d + -2d

Combine like terms: 2d + -2d = 0
6 + -2d = 2 + 0
6 + -2d = 2

Add '-6' to each side of the equation.
6 + -6 + -2d = 2 + -6

Combine like terms: 6 + -6 = 0
0 + -2d = 2 + -6
-2d = 2 + -6

Combine like terms: 2 + -6 = -4
-2d = -4

Divide each side by '-2'.
d = 2

Simplifying
d = 2
