Step-by-step explanation:
Answer
5x−6y=2 ------- (1)
6x−5y=9 ------ (2)
From equation 1:
6y=5x−2
y=
6
5x−2
Substitute the value of y in equation 2 :
6x−5y=9
6x−5(
6
5x−2
)=9
36x−25x+10=54
11x=54−10
X=
11
44
=4
Now, Substitute x=4 in equation 1 :
5x−6y=2
5×4−6y=2
20−2=6y
18=6y
y=
6
18
=3
Therefore the solution is: x=4 and y=3

Answer:
5x−6y=2 ------- (1)
6x−5y=9 ------ (2)
From equation 1:
6y=5x−2y= 65x−2
Substitute the value of y in equation 2 :
6x−5y=96x−5( 65x−2 )=9
36x−25x+10=54
11x=54−10
X= 44/11=4
Now, Substitute x=4 in equation 1 :
5x−6y=2
5×4−6y=2
20−2=6y
18=6y
y= 18/6=3
Therefore the solution is: x=4 and y=3
