Ionly have 2 questions i need with them plz i'll mark you as brainliest.
1. explain how system 1 becomes equivalent to system 2.
system 1:
lx + my = n
ax + by = c
system 2:
(l − a)x + (m − b)y = n − c
lx + my = n
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.
b. 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.
c. the first equation in system 2 is the difference of the equations in system 1. the second equation in system 2 is the first equation in system 1.
d. the first equation in system 1 is the sum of the equations in system 2. the second equation in system 1 is the first equation in system 2.
2. create an equivalent system of equations using the sum of the system and the first equation.
−3x + y = 12
x + 3y = 6
a.−3x + y = 12
−2x + 4y = 18
b. −3x + y = 12
−3x + 4y = 18
c.−3x + y = 12
x + 4y = 18
d.−3x + y = 12
−2x + 4y = 6
