Question

In which quadrant the solution of 2x+3y = 5 and 7x+12y = 19 lie?

​

Answer 1

Answer:

For solving equations, first multiply the 1st equation with 7 and 2nd equation with 2.

After solving, you get

(x,y) = (1,1)

In this point, both x and y coordinates are > 0. So, this point lies in 1st quadrant.

Answer 2

question :-

In which quadrant the solution of 2x+3y = 5 and 7x+12y = 19 lie?

answer:-

Since (3,a) lie on the line 2x - 3y = 5 ...(1)

Substituting x=3 and y=a in (1) we get

2(3) - 3(a) = 5

6 - 3a = 5

⇒3a=1

⇒a=1/3
