The equation in the image is:

$10 + 10(x + 3) = -x - 10(-x + 1)$

Let's solve it step by step:

Step 1: Expand both sides.

Expand the terms with parentheses:

$10 + 10(x + 3) = 10 + 10x + 30 = 10x + 40$

On the right side:

$-x - 10(-x + 1) = -x + 10x - 10 = 9x - 10$

So the equation becomes:

$10x + 40 = 9x - 10$

Step 2: Collect like terms.

Move all the terms involving $x$ to one side and constant terms to the other side:

$10x - 9x = -10 - 40$

Simplify:

$x = -50$

Final solution:

The solution to the equation is:

$x = -50$
