Question

According to 9th ncert lesson 'Coordinate Geometry' ------find a and b if (2a+3 , 5) = (9 , b-2) . Will mark as brainliest....​

Answer 1

Answer:

a=3 and b=7

2a+3=9

6=b-2

Answer 2

As we knows if pair of cordinates are equal then each coordinates are equal

i. e

(a, b) = (x, y) yhen a=x and b=y

applying

2a+3=9........(1)

and

5= b-2.........(2)

on solving(1)

2a = 6

-----> a=6/2

------> a =3

on solving (2)

5+2=b

-------> b = 7
