Explain how system 1 becomes equivalent to system 2.
system 1:
ax + by = c
lx + my = n
system 2:
(a + l)x + (b + m)y = c + n
ax + by = c

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
