4x=4x4
3x2+10=16
What are the numbers for A,b,c,d
Hey there!
Here is your question -

In this equation, you're looking for n alone. To keep the variable alone, you have to do the opposite of what's happening to the variable.
In this equation, 12 is being added to n. The opposite of that is subtracting 12.
Subtract 12 from both sides -

Your answer is -8.
Hope this helps! :)
The distributive property says that a(b+c)= ab+ac
3(2y-7)= 3(2y)+ 3(-7)
Final answer: 6y-21
Hoi!
Here's how you would write this.
z - 34.7 = 68.2
"Less than" indicates subtraction, but from what? "Less than z", so we're subtracting something from z. If you look at the equation, how would we calculate 34.7 less than z? To do this, we would subtract 34.7 from z. Since we're given our answer to the equation, just slap that into the equation after an "equals" symbol, and you're finished!
