To determine the value of x in the equation x + 9 = 11, you need to isolate x on one side of the equation. Here's how you can solve it:
Step 1: Subtract 9 from both sides of the equation:
x + 9 - 9 = 11 - 9
x = 2
Therefore, the value of x is 2.
Now let's move on to the second equation: m - 6 = 15.
Step 1: Add 6 to both sides of the equation:
m - 6 + 6 = 15 + 6
m = 21
Hence, the value of m is 21.
Lastly, let's work on the equation -72 = 6w.
Step 1: Divide both sides of the equation by 6:
-72 ÷ 6 = (6w) ÷ 6
-12 = w
So, the value of w in the equation is -12.
