Answer:
The length of the two pieces are 41 in and 24 in
Step-by-step explanation:
Let
x -----> the length of one piece
y ----> the length of the other piece
we know that
-----> equation A
-----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the two pieces are 41 in and 24 in
First, distribute the -3(-2x + 1).
-3 x -2x = 6x -3 x 1 = -3 -3(-2x + 1) = 6x - 3
Now we have:
9 - 5 1/2x + 6x - 3
Combine like terms.
-5 1/2x + 6x = 1/2x 9 - 3 = 6
The two terms we are left with are 1/2x and 6.
The simplified version of this expression is 1/2x + 6.
Hope this helps!
