Respuesta :

2x + 4y = 14
Multiply the equation by 3, 
6x + 12y = 42
Now, subtract it from 1st, 
3x = -9
x = -3

Substitute the value in 1st equation, 
2(-3) + 4y = 14
-6 + 4y = 14
4y = 14 + 6
y = 20/4
y = 5

In short, Your Answer would be Option B) (-3, 5)

Hope this helps!

The order pair that represent the solution is (-3, 5), the correct option is B.

What is System of Equation?

The system of equation is set of equations which have a common solution.

The system of equation is

2x+4y = 14

3x+12y =51

To solve the system

2x = 14-4y

x = 7- 2y

Substituting this value in equation 2

3 *( 7 -2y ) +12y = 51

21 -6y +12y =51

6y = 30

y =5

x = 7 - 2 * 5

x = -3
