Question

(a+2,4)=(5,2a+b)then a=?,b=?

Answer 1

Answer:

a=3

b= -2

Step-by-step explanation:

Given(a+2, 4) = (5, 2a+b)

So, a+2=5 --(1)

4= 2a+b --(2)

From equation (1)

a=3

Putting a=3 in equation (2)

We get

b= -2

Answer 2

Answer:a=3, b= -2

Step-by-step explanation:Since the two ordered pairs are equal, a+2=5 So a=5-2=3. Also 2a+b=4. So b=4-2a. Hence b=4-2*3. So b=4-6. And b=-2
