System A) x + 3y = -9
2x + y = 4
system B) 3x + 4y = -9
2x + y = 4
1) How can we get System B from System A?
Choose 1
a) Replace one equation with the sum/difference of both equations
b)Replace only the left-hand side of one equation with the sum/difference of the left-hand sides of both equations
c)Replace one equation with a multiple of itself
d) Replace one equation with a multiple of the other equation
2) based on the previous answer, are the systems equivalent? in other words, do they have the same solution?
A) yes
B) No
