Answer 3

Let's break down the given equations step by step and solve for the values of a and b:

1. B = 5
2. a = -3
3. b = 7 + a * b
4. b = a/2 + b

We'll start with the first two equations, which give us the values of B and a:

From equation 1: B = 5 From equation 2: a = -3

Now, let's substitute these values into the remaining equations:

3. b = 7 + a * b Substituting a = -3: b = 7 + (-3) * b

4. b = a/2 + b Substituting a = -3: b = (-3)/2 + b

Now, we can solve these equations for b:

3. b = 7 + (-3) * b Simplify: b = 7 - 3b

   Add 3b to both sides: 4b = 7

   Divide by 4: b = 7/4

4. b = (-3)/2 + b Simplify: b = (-3)/2 + 7/4

   To add these fractions, find a common denominator: b = (-6/4) + (7/4)

   Now, add the fractions: b = (7 - 6)/4 b = 1/4

So, the solutions for a and b are:

• a = -3
• b = 1/4
