Respuesta :

Answer:

D

Step-by-step explanation:

i took this test.

The system of equation A can be modified as system B, and the modified equations are -x - 2y = 7 and-16y = 32 solutions to the system of equation is (-3,-2) option (D) is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have two linear equations:

System A

-x - 2y = 7

5x - 6y = -3

From equation A:

x = -2y - 7

Plug this value in the equation second.

5(-2y - 7) - 6y = -3

-10y - 35 - 6y = -3

-16y = -3 + 35

-16y = 32

System B

-x - 2y = 7

-16y = 32

y = - 2

x = -3

Solutions:(-3,-2)

Thus, the system of equation A can be modified as system B, and the modified equations are -x - 2y = 7 and-16y = 32 solutions to the system of equation is (-3,-2) option (D) is correct.
