Solution:-
2x+3y=15........(1)
x= (15-3y)/2.........(2)
5x+8y=56......(3)
puting x's value in eq(3)
= 5×(15-3y)/2 +8y = 56
= (75 -15y)/2 +8y = 56
= 75-15y+16y = 112
= (y = 37)ans
putting y's value in eq(1)
2x + 3×37 = 15
x = -96/2
(x= -48)ans
2x+3y=15........(1)
x= (15-3y)/2.........(2)
5x+8y=56......(3)
puting x's value in eq(3)
= 5×(15-3y)/2 +8y = 56
= (75 -15y)/2 +8y = 56
= 75-15y+16y = 112
= (y = 37)ans
putting y's value in eq(1)
2x + 3×37 = 15
x = -96/2
(x= -48)ans
