Answer:
a) 2L + 2W = 42
b) L = 2W + 3
c) The system is :
2L + 2W = 42
L - 2W = 3
( add the two equations )
3L + (2w - 2w) = 45
3L = 45
L = 45/3
L = 15 ( Length )
L - 2W = 3
15 - 2W = 3
2W = 15 - 3
W = 12/2
W = 6

Step-by-step explanation:
Answer:
Step-by-step explanation:
The given system of linear equations is:
We have to solve the equations for the values of 
.
Let us use elimination method in which we eliminate one of the variables from the two variables.
For this, let us multiply the first equation by 
and second equation by 
Now, the equations become:
Now, let us add (1) and (2):
Using the equation:
Putting value of 
:
So, the answer to the system of linear equations is:
