Question

les :add what to both sides?
$22 + \square = 10x + 14 + \square$

Explanation:

Step1: Identify goal (isolate x terms)

To balance and simplify, we can add $-14$ to both sides to eliminate the constant 14 on the right, or add $10x$ to both sides to get x terms on the left. The most standard step here is to eliminate the constant on one side first.

Step2: Apply additive inverse

We add $-14$ (or subtract 14, which is equivalent) to both sides to keep the equation balanced.
$22 + (-14) = 10x + 14 + (-14)$
Alternatively, to collect x terms, we could add $-10x$ to both sides:
$22 + (-10x) = 10x + 14 + (-10x)$
The most common first step for solving for $x$ is removing the constant from the variable side, so using $-14$ is typical.

Answer:

The left blank: $\boldsymbol{-14}$ (or $\boldsymbol{10x}$), the right blank: $\boldsymbol{-14}$ (or $\boldsymbol{10x}$)
(The standard choice for solving the equation is adding $\boldsymbol{-14}$ to both sides)
