LET 4X +9Y=5 BE EQUATION 1
AND 3X-5Y=39 BE EQUATION 2
THEREFORE, MULTIPLYING EQUATION 1 BY 5 AND EQUATION 2 BY 9 AND ADDING BOTH EQUATIONS
HENCE, 20X+45Y=25
27X-45Y=351
BY SOLVING WE GET:-
47X=376
THEREFORE, X=8
putting value of x in equation 1
4(8)+9y=5
32+9y=5
9y=(-27)
Y=(-3)
VALUE OF X IS 8 AND Y IS (-3)
