Question

i cant solve this pls help
5y=6x+2,6y-5x=9​

Answer 1

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

Answer 2

Answer:

x=3 and y= 4

Step-by-step explanation:

First re arrange the equations.

$6x - 5y = - 2$

and

$5x - 6y = - 9$

Now use method of comparing coefficient of one of the variable x or y. lets multiply equation 1 with 5 and equation two with 6. then equations will become.

$30x - 25y = - 10$

and

$30x - 36y = - 54$

Now subtracting equation 2 from equation 1.

$11y = 44 \\ y = 4$

use this value in one the equation to get value of the x. lets put in equation 1 written in the start. $6(x) - 5(4 ) = - 2 \\ 6x = - 2 + 20 \\ = 18 \div 6 = \\ = 3\\x=3$
