Which system has the same solution as the system of equation shown
8x + 3x =5
4x + 2y =3

a. 8x+3y=5
-8x + 4y= -6

b. 8x+3y=5
-8x - 4y= -6

c. 16x + 6y =5
12x - 6y = 9

d. 8x + 3y=5
8x + 4y= 3

B. 8x+3y=5

-8x - 4y= -6

Step-by-step explanation:

The given system of equations is expressed as

8x + 3y =5 - - - - - - - - -1

4x + 2y =3 - - - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 4 and equation 2 by 8. It becomes

32x + 12y =20

32x + 16y = 24

Subtracting, it becomes

- 4y = - 4

y = - 4/ - 4

y = 1

Substituting y = 1 into equation 1. It becomes

8x + 3 × 1 =5

8x + 3 = 5 - 3 = 2

x = 2/8 = 1/4

Substituting x = 1/4 and y = 1 into the given options, it becomes

A. 8 × 1/4 + 3 × 1=5

2 + 3 = 5

- 8 × 1/4 +4 × 1 = 2

B. 8x+3y=5

-8x - 4y= -6

- 8 × 1/4 - 4 × 1 = -6

Therefore, the system of of equations that has the same solution as the given equation is

B. 8x+3y=5

-8x - 4y= -6

won't that be plagrisim thought?

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
