not sure about this can someone please help me
solve for x using the addition principle
x+10=-13
Now I added 10 to both sides 10 + 10 that gives me 20
then I added -13 +10 = -3
my x is the 20 or did I mess this problem up all the way around?
You need to subtract (not add) 10 to both sides of the equation. The purpose is to get the unknown quantity on one side and the known quantity on the other side.
x + 10 - 10 = -13 + (-10)
x = -23
you -10 from both sides not add
[do the opposite]
so x=-23
To solve for x using the addition principle, follow these steps:
1. Start with the equation: x + 10 = -13
2. The goal is to isolate the variable x on one side of the equation, so we need to get rid of the 10 on the left side.
3. To do this, subtract 10 from both sides of the equation: (x + 10) - 10 = -13 - 10.
This simplifies to: x = -23.
Therefore, the solution to the equation x + 10 = -13 is x = -23. You have made an error when performing the calculations in your attempt. The correct solution is x = -23, not x = 20 or x = -3.
