1. Problem Description

Solve the equation 5x+4=2x245x + 4 = -2x - 24 for xx.

2. Solution Steps

The given equation is 5x+4=2x245x + 4 = -2x - 24.
First, add 2x2x to both sides of the equation:
5x+2x+4=2x+2x245x + 2x + 4 = -2x + 2x - 24
7x+4=247x + 4 = -24
Next, subtract 4 from both sides of the equation:
7x+44=2447x + 4 - 4 = -24 - 4
7x=287x = -28
Finally, divide both sides of the equation by 7:
7x7=287\frac{7x}{7} = \frac{-28}{7}
x=4x = -4

3. Final Answer

x=4x = -4
