J) Is m=5 a solution to this equation? 2=7-m yes no

## Step 1: Substitute $m = 5$ into the equation<br />### Replace $m$ with $5$ in the equation $2 = 7 - m$.<br />## Step 2: Simplify the equation<br />### Perform the subtraction $7 - 5$ to see if it equals $2$.<br /><br />\[<br />2 \stackrel{?}{=} 7 - 5<br />\]<br /><br />## Step 3: Verify the equality<br />### Calculate $7 - 5$ and check if it equals $2$.<br /><br />\[<br />2 \stackrel{?}{=} 2<br />\]<br /><br />Since both sides of the equation are equal, $m = 5$ is a solution.
