Question

6y-3=3(y+1)+9 find y​

Answer 1

Step-by-step explanation:

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

∴ the solution is x=4 and y=3
