Answer
Consider given equations
x
2
−
y
3
=15 ………….(1)
x
8
+
y
5
=77 ………….(2)
Let,u=
x
1
,v=
y
1
then, we get
2u-3v=15 ……………..(3)
8u+5v=77 ………………(4)
From equation (3) u=
2
15+3v
put in equation (4), we get
8×(
2
15+3v
)+5v=77
4(15+3v)+5v=77
60+12v=77
v=
12
17
Put the value of v in equation (3).
2u−3×
12
17
=15
2u=15+
4
17
=
4
77
u=
8
77
Now,
x
1
=u,
y
1
=v
x
1
=
8
77
,
y
1
=
12
77
x=
77
8
,y=
77
12
Hence, this is the answer,
