Question

1) a - b = -3 2) a-b=0 3) b-a=1​

Answer 1

1) a - b = -3
a = -3 + b
a = b - 3
2) a - b = 0
a - b + b = 0 + b
a = b
3) b - a = 1​
b = 1 + a
b = a + 1

Answer 2

Let's solve the system of equations:

1. a - b = -3
2. a - b = 0
3. b - a = 1

We can start with equation 1:

a - b = -3

Now, let's solve equation 2:

a - b = 0

Equation 2 implies that a and b are equal, so we can rewrite it as:

a = b

Now, let's use equation 3:

b - a = 1

Since we know that a = b from equation 2, we can substitute:

b - b = 1

This simplifies to:

0 = 1

However, the equation 0 = 1 is not true. Therefore, there is no solution that satisfies all three equations simultaneously. The system of equations is inconsistent.
