Equations X Minus 2 1E19Ff

1. **State the problem:** We need to find which equations have $x=-2$. 2. **Check each equation by substituting $x=-2$: ** - For $7-5=x$, calculate $7-5=2$, which is not $-2$. - For $-1-1=x$, calculate $-1-1=-2$, which equals $x$. - For $10-8=x$, calculate $10-8=2$, which is not $-2$. - For $-5+3=x$, calculate $-5+3=-2$, which equals $x$. - For $-8+10=x$, calculate $-8+10=2$, which is not $-2$. 3. **Conclusion:** The equations where $x=-2$ are $-1-1=x$ and $-5+3=x$. **Final answer:** $-1-1=x$ and $-5+3=x$ have $x=-2$.
