Will give best answer!!Use the elimination method to solve the system of equations. Choose the correct ordered

7x + 4y = 39
2x + 4y = 14

A. (5, 4)
B. (3, 2)
C. (5, 1)
D. (3, 4)

7x+4y=39,
2x+4y=14,
----------------
7x+4y=39,
-(2x+4y)=-14,
--------------------
7x+4y=39,
-2x-4y=-14,
-----------------
5x=25,
x=25/5=5,
7(5)+4y=39,
35+4y=39,
4y=39-35,
4y=4,
y=4/4=1.
Answer: x=5, y=1. (5, 1). C.

Can someone answer my easy question?

7x+4y=39
2x+4y=14
If the signs are same (plus, minus, divide or multiply) then u subtract both equations
If they are different u add em.
Same sub
Diff add
They are same so we subtract
7x+4y=39 - 2x+4y=14
7x-2x=5x
4y-4y=0
39-14=25
5x = 25
Divide both sides by 5 to get X by itself
X=5
Now enter x=5 into one of the equations
Ill do the top 1
7x+4y=39
35+4y=39
Take away 35 on each side
4y=4
Divide both sides by 4 to get Y by itself
Y=1

X=5 and Y=1

7x + 4y = 39 [Equation 1]

2x + 4y = 14 [Equation 2]



Multiply equation 1 by -1

-7x -4y = -39
2x + 4y = 14


Add equation 2 to equation 1


-5x= -25

2x+4y=14


Divide both sides of equation 1 by -5


x=5

2x+4y=14


Substitue equation 1 (x=5) into equation 2.


2(5)+4y=14

10+4y=14

4y=4

y=1.



THE ANSWER IS C.(5,1). <======================
