n+10=2(n+3)

Solution for n+10=2(n+3) equation:

Simplifying
n + 10 = 2(n + 3)

Reorder the terms:
10 + n = 2(n + 3)

Reorder the terms:
10 + n = 2(3 + n)
10 + n = (3 * 2 + n * 2)
10 + n = (6 + 2n)

Solving
10 + n = 6 + 2n

Solving for variable 'n'.

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

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

Combine like terms: n + -2n = -1n
10 + -1n = 6 + 2n + -2n

Combine like terms: 2n + -2n = 0
10 + -1n = 6 + 0
10 + -1n = 6

Add '-10' to each side of the equation.
10 + -10 + -1n = 6 + -10

Combine like terms: 10 + -10 = 0
0 + -1n = 6 + -10
-1n = 6 + -10

Combine like terms: 6 + -10 = -4
-1n = -4

Divide each side by '-1'.
n = 4

Simplifying
n = 4
