Answer two questions about Systems A and B: System A
- 2x + 5y = 10
-3x + 9y = 6
System B
-3x + 9y = 6
- 2x + 5y = 10
1) How can we get System B from System A?
A. Replace one equation with a multiple of the other equation
B. Replace one equation with a multiple of itself
C. Swap only the left-hand sides of both equations
D. Swap the order of the equations

2) base on the previous answer equivalent? I the other words, do they have the same solutions
Yes or no

swap the order of the equations

Step-by-step explanation: and yes it is the same solution it’s equal. Did this on khan academy

i can confirm that the answer above is correct

Step-by-step explanation:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
