1. Problem Description

We are asked to solve the linear equation 5+2(x+5)=45x5 + 2(x+5) = 4 - 5x for xx.

2. Solution Steps

First, we distribute the terms on both sides of the equation.
5+2(x+5)=45x5 + 2(x+5) = 4 - 5x
5+2x+10=45x5 + 2x + 10 = 4 - 5x
Next, we combine like terms on the left side of the equation.
15+2x=45x15 + 2x = 4 - 5x
Then, we add 5x5x to both sides of the equation.
15+2x+5x=45x+5x15 + 2x + 5x = 4 - 5x + 5x
15+7x=415 + 7x = 4
Now, we subtract 15 from both sides of the equation.
15+7x15=41515 + 7x - 15 = 4 - 15
7x=117x = -11
Finally, we divide both sides of the equation by 7 to solve for xx.
7x7=117\frac{7x}{7} = \frac{-11}{7}
x=117x = -\frac{11}{7}

3. Final Answer

x=117x = -\frac{11}{7}
