n+3=2(n+10)

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

Simplifying
n + 3 = 2(n + 10)

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

Reorder the terms:
3 + n = 2(10 + n)
3 + n = (10 * 2 + n * 2)
3 + n = (20 + 2n)

Solving
3 + n = 20 + 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.
3 + n + -2n = 20 + 2n + -2n

Combine like terms: n + -2n = -1n
3 + -1n = 20 + 2n + -2n

Combine like terms: 2n + -2n = 0
3 + -1n = 20 + 0
3 + -1n = 20

Add '-3' to each side of the equation.
3 + -3 + -1n = 20 + -3

Combine like terms: 3 + -3 = 0
0 + -1n = 20 + -3
-1n = 20 + -3

Combine like terms: 20 + -3 = 17
-1n = 17

Divide each side by '-1'.
n = -17

Simplifying
n = -17
