Explain how System 1 becomes equivalent to System 2.


System 1:

Ax + By = C

Lx + My = N


System 2:

Ax + By = C

(A − L)x + (B − M)y = C − N


The first equation in System 1 is the sum of the equations in System 2. The second equation in System 2 is the first equation in System 2.

The first equation in System 1 is the difference of the equations in System 2. The second equation in System 1 is the first equation in System 2.

The second equation in System 2 is the sum of the equations in System 1. The first equation in System 2 is the first equation in System 1.

The second equation in System 2 is the difference of the equations in System 1. The first equation in System 2 is the first equation in System 1.

Respuesta :

Answer:

Equivalent expressions are expressions that have the same value.

Step-by-step explanation:

The true statement is: (a) The first equation in System 2 is the sum of the equations in System 1. The second equation in System 2 is the first equation in System 1.

The systems of equations are:

System 1

System 2

When the equations of system 1 are added, we have:

Factor out x and y

The above equation is the first equation of system 2.

While  is the second equation of the system

Hence, the true statement is (a)
