To solve for x in the equation 2x + 3x + 4 + 5 = 0, we first need to combine like terms.
1. Combine the x terms:
- 2x + 3x = 5x
This modifies our equation to:
5x + 4 + 5 = 0
2. Next, add the constant terms:
- 4 + 5 = 9
So now we have:
5x + 9 = 0
3. To isolate x, subtract 9 from both sides:
- 5x = -9
4. Finally, divide both sides by 5:
- x = -9/5
So, the solution for x in the equation 2x + 3x + 4 + 5 = 0 is:
x = -1.8
This means that the value of x that balances the equation is -1.8.
