Let’s dive into the fascinating world of algebraic expressions!

When you see an equation like , it showcases the distributive property in action. This property states that you can distribute a multiplication over addition or subtraction, like turning into . So, in , you can simply calculate .

Now, for the second equation, we can find the missing part. Since , the expression becomes . To make both sides equal, the missing value is 2 (as , which is ).

The fun doesn’t stop there! If you take a look at , you’re using the same principle. The sum within the brackets adds up to 39, so you’re effectively saying . Here, to balance the equation, the missing number is 24 (because ).

And finally, in , subtracting gives you 7, so this becomes . To solve for the missing value, we see that it is 11 (since ).

In summary, the missing numbers are 2, 24, and 11! Now doesn’t that make algebra just a touch more exciting?
