Solve for m: m - 17 = 22

Step 1

Given equation: m - 17 = 22

Add 17 to both sides of the equation and simplify.

⇒ m−17+17 = 22+17

⇒ m = 39

So, the value of m is 39.

Explanation:

Here, we add 17 from both sides of the equation to keep it balanced and simplified. Therefore, the solution to the equation m − 17 = 22 is m = 39.
