5a -3b=9
Select one:
a. (2,-3)
b. (-3,2) Incorrect
c. (3,2)
d. (2,3)

Answer 1

if you add both equation you end up with 7a=21 because 3b-3b cancel out...then you get the value of a...after this if you put the value of 'a' in any of two equation you can solve for 'b'..

Answer 2

c is the correct answer...i hope you got it...
