If the ordered pairs (a +2,4) and (5,2a + b) are equal then (a,b) is(1(2.-2) (2) (5.1)(3) (2,3)(4) (3,-2) explain it​

Answer»

Answer:

Answer is (4) part.

EXPLANATION :

If ordered PAIRS are EQUAL, then there domain and range are ALSO equal.

So, a+2=5

So, a=5-2

a=3

Now 4=2a+b

Putting the value of a, we GET;

4=3×2+b

So,4=6+b

Therefore b=-2.

HOPE IT IS HELPFUL! ☺️☺️☺️
