Consider the following system. 2x - 5y = 6
3x + 2y = 4
If the system was to be solved using elimination, which would be correct factors to multiply each equation by
to eliminate the variable x?
а
4.(2x - 5y) - (6.4
6. (3x + 2y) = (4) --6
c. 2. (2x - 5y) = (6) 2
5-(3x + 2y) - (4) - 5
b.
3. (2x - 5y) = (6) 3
-2. (3x + 2y) = (4). -2
d 2- (2x - 5y) = (6) -2
-5 (3x + 2y) = (4) -5
