Hatshy [7]
X - y  = 2400/6 = 400        where x = speed of plane and y = speed of wind.

x + y =  2400/5 = 480          - flying with the wind

adding the 2 equations 
2x = 880

How do I do pre-Algebra???
Lana71 [14]

Hey there!

The main concept of pre-algebra is solving equations for variables in them.

For example, let's say you have the algebraic equation below.

x+1=3

With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.

We would subtract 1 to both sides to isolate x on one side.

x+1-1=3-1

As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.

x=3-1

x=2

Therefore, in our equation x+1=3, x would be equal to 2.

I hope this explanation helps! Have a great time here at Brainly!
