Question

4x-3y=6 and 7x=5y=31 solve in any method

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

(4x-3y)×5-(7x-5y)×3=6×5-31×3

➡. 20x-15y-21x+15y=30-93

➡. 20x-21x=. -63

➡. -x. =. -63

➡. x. =. 63

Now,

Eq no 2

7x-5y=31

➡. 7×63-5y=31. (substitute value of x)

➡. 441-5y=31

➡. -5y=. 31-441

➡. -5y=. -410

$= > - y = \frac{ - 410}{5} \\ = > - y = - 82 \\ = > y = 82$

Answer:-

x=63

y =. 82
