Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v + y - n = 5
N = 0 + y - n = 5
In short, N would be equal to y - n which is still equal to 5
Hope this helps!

The growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.
<h3>What is linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The normal yearly growth of a plant is 60 inches.
Let's suppose the growth of the plant last year was x
The normal growth was ten inches more than twice the amount of last year.
From the above statement:
10 + 2x = 60
2x = 50
x = 25 inches
Thus, the growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.

Answer:
(1/4) hr/mile
Step-by-step explanation:
4 mph can be rewritten using other units of measurement:
Suppose we convert 'miles' to 'feet:'
Then:
4 miles 5280 ft
---------- * ------------- = 21120 ft/hr
1 hr 1 mile
Note that we could invert 4 mph and obtain
1 hr
-------- or (1/4) hr/mile
4 mi
100% markup means the price is double what it was bought for, $30. 30x2=60 dollar sale price. A 20% commision would be $12. 60 x 0.2=12
