Move the dots along the number line to determine the unknown value in the given number sentence - 6 - _____ = 8

Answer 1

To solve the equation \( 6 - x = 8 \), we need to isolate \( x \).

First, we can rearrange the equation:

\[ 6 - x = 8 \]

Subtract 6 from both sides:

\[ -x = 8 - 6 \]

This simplifies to:

\[ -x = 2 \]

Now, to find \( x \), we multiply both sides by -1:

\[ x = -2 \]

So, the unknown value is \( -2 \). Therefore, the complete equation is:

\[ 6 - (-2) = 8 \]

This checks out, as \( 6 + 2 = 8 \).
