1) Is n=3 a solution to this equation? 5-n=2 yes no

## Step 1: Substitute $n = 3$ into the equation<br />### Replace $n$ with $3$ in the equation $5 - n = 2$. This gives $5 - 3 \stackrel{?}{=} 2$.<br />## Step 2: Simplify the left-hand side<br />### Perform the subtraction: $5 - 3 = 2$. Now, check if $2 = 2$.<br />## Step 3: Verify the equality<br />### Since $2 = 2$ is true, $n = 3$ satisfies the equation.
