If $(a,4) = (-2,a+b)$, find a and b.

Given :

The given expression is $(a, 4) = (-2, a+b)$

To do :

We have to find the value of a and b.

Solution :

We know that,

Two ordered pairs are equal if and only if the corresponding first components are equal and the second components are equal. 

Therefore,

$a = -2$ and $4 = a+b$

$-2+b = 4$

$b=4+2$

$b=6$

The values of a and b are $-2$ and 6 respectively.
