Answer 1

You need the steps written out to how the answer ended up being 21?

Answer 2

You start by simplifying. 6(2x + -11) + 15 = 21
Reorder each of your terms; 6(-11 + 2x) + 15 = 21
From that problem, you will order it to look like this, (-11 * 6 + 2x * 6) + 15 = 21
-11 * 6 plus 2x * 6 + 15 will make your problem look like this: (-66 + 12x) + 15 = 21
From here you will reorder your terms now, -66 + 15 + 12x = 21
Combine your like terms now, -66 + 15 = -51 which makes it be -51 + 12x = 21
------------------------------------------------------------------------
To solve for x now, Move all terms containing x to the left, all other terms to the right.

Add '51' to each side of the equation.
-51 + 51 + 12x = 21 + 51

Combine like terms: -51 + 51 = 0
0 + 12x = 21 + 51
12x = 21 + 51

Combine like terms: 21 + 51 = 72
12x = 72

Divide each side by '12'.
x = 6

Simplifying
x = 6
