If it's possible to tell, decide if a and b are positive or negative: a-3>b-3 and b>4

Svetllana [295]

Answer:

a and b are positive

Step-by-step explanation:

We are given that

$a-3>b-3$

$b>4$

We have to find that a and b are positive or negative.

We have

$b>4$

It means b is positive and greater than 4.

$a-3>b-3$

Adding 3 on both sides

$a-3+3>b-3+3$

$a>b>4$

$\implies a>4$

Hence, a is positive and greater than 4.

Therefore, a and b are positive
