Question

Explain how System 1 becomes equivalent to System 2.

Answer 1

Answer:

In the procedure

Step-by-step explanation:

we have

System 1

Ax+By=C -----> equation A

Lx+My=N -----> equation B

step 1

Adds equation A and equation B

Ax+By=C

Lx+My=N

----------------

Ax+Lx+By+My=C+N

(A+L)x+(B+M)y=C+N -----> equation C

step 2

An equivalent system (System 2) is formed with equation C and equation A

(A+L)x+(B+M)y=C+N -----> equation C

Ax+By=C -----> equation A
