1. Problem Description

We need to solve the equation 4x2(x+1)=5(x+3)+54x - 2(x+1) = 5(x+3) + 5 for xx.

2. Solution Steps

First, we expand both sides of the equation:
4x2(x+1)=5(x+3)+54x - 2(x+1) = 5(x+3) + 5
4x2x2=5x+15+54x - 2x - 2 = 5x + 15 + 5
2x2=5x+202x - 2 = 5x + 20
Next, we subtract 2x2x from both sides:
2x22x=5x+202x2x - 2 - 2x = 5x + 20 - 2x
2=3x+20-2 = 3x + 20
Now, we subtract 2020 from both sides:
220=3x+2020-2 - 20 = 3x + 20 - 20
22=3x-22 = 3x
Finally, we divide both sides by 33 to isolate xx:
223=3x3\frac{-22}{3} = \frac{3x}{3}
x=223x = -\frac{22}{3}

3. Final Answer

x=223x = -\frac{22}{3}
