- 10x + 18 + 2x = - 5

Starting with the given equation:

-10x + 18 + 2x = -5

We can simplify by combining like terms on the left side:

-8x + 18 = -5

Next, we can isolate the variable by subtracting 18 from both sides:

-8x = -5 - 18
-8x = -23

To solve for x, we divide both sides by -8:

x = -23 / -8

This can be simplified further as:

x = 23/8 or 2.875

Therefore, the solution to the equation is x = 2.875.
