Answer
$a = 13$
Work Step by Step
Given the equation:
$-23 = -2a - 10 + a$
We start by combining like terms together as shown below:
$-23 = -2a + a - 10$
Simplify to get:
$-23 = -a - 10$
Next, we isolate the variable $a$ by adding $10$ to both sides of the equation as shown below:
$-23 + 10 = -a - 10 + 10$
Simplify to get:
$-13 = -a$
Now, we divide through by $-1$, which is the coefficient of the variable $a$ in the equation:
$\frac{-13}{-1} = \frac{-1}{-1}a$
Simplifying, we have:
$13 = a$
Rearranging, we have:
$a = 13$
Therefore, the equation has a possible solution at the point $a = 13$
