Answer:
D.
Step-by-step explanation:
2 is it's length while in the perinthesis is x for its length plus the width which is doubled, explained by the x.
Alright so after solving it the answer would be x=2 and y= 6
To solve, divide the dollars by the pounds of peanuts to find the cost per pound:
12/8 =1.5
So, it cost $1.50 per pound of peanuts.

Answer:
(8,-1)
Step-by-step explanation:
Given : 

To Find: solution of given system of equations.
Solution:
Equation a : 
Equation b : 
Substitute the value of y from equation b in equation a
y from equation b : y = 7-x
Now substitute value of y in equation a
Thus equation a becomes:







⇒ x= -1 and x = 8
Now substitute values of x in equation b to obtains values of y
⇒ 
for x = -1
⇒ 
⇒ 
⇒ 
Thus (x,y)=(-1,8)
For x =8
⇒ 
⇒ 
⇒ 
Thus (x,y)=(8,-1)
Hence Option A is the correct solution .
Solve for x.
First multiply everything in the parenthesis by 3.
12 + 12x = 12 + 12x
There is an infinite amount of solutions.
