Answer: N=15

Step-by-step explanation: This is because (4n-18) when solved needs to equal 42. So when solving this you would change the equation to 42=4n-18 and then you need to isolate n. In order to do that you do the opposite so your equation becomes 42+18=4n or (60)=4n. And then you divide 60/4 and get n by itself. Therefore N=15.

John likes to watch the birds in her yard. One morning, she noticed that there are twice as many Robbins as Blue Jays. She count

Degger [83]

We can write an equation to solve this:

Let x represent amount of Blue Jays.

2x + x = 21

We can simplify the equation:

3x = 21

Divide both sides by 3 to isolate x variable:

x = 7

Therefore, 7 Blue Jays.
