3х+5+(х+5)=(1-х)+4

Let's solve the equation step by step:

The equation is:

\[ 3x + 5 + (x + 5) = (1 - x) + 4 \]

First, simplify both sides of the equation.

On the left side:

\[ 3x + 5 + x + 5 = 3x + x + 5 + 5 = 4x + 10 \]

On the right side:

\[ (1 - x) + 4 = 1 - x + 4 = 5 - x \]

Now, the equation looks like this:

\[ 4x + 10 = 5 - x \]

Next, add \(x\) to both sides:

\[ 4x + x + 10 = 5 - x + x \]

This simplifies to:

\[ 5x + 10 = 5 \]

Now, subtract 10 from both sides:

\[ 5x + 10 - 10 = 5 - 10 \]

This simplifies to:

\[ 5x = -5 \]

Now, divide both sides by 5:

\[ x = -1 \]

So, the solution to the equation is:

\[ x = -1 \]
