Question

If the point of intersection of 2x + 3y = 19 and 5x + 4y = 37 is (a, 3), then
a =
(1) 5
(2)-5
(3) 4
(4) -4 ​

Answer 1

Step by step explanation

when you input value of y as 3 in any of the equations mentioned above the value of a would also be 5.

2x+3(3)=19

2x=10

x=5

If you try out at the other equation:

5x+4(3)=37

5x=25

x=5

So the answer always comes out to be 5.
