Answer:
(a) Because the expression is not an equation
(b) Because the expression is an equation
Step-by-step explanation:
Solving (a): a + 2
The above expression can assume any value for a because it is not an equation.
Take for instance:
a = 2;
<em>The reason for this is because the expression is not an equation</em>
Solving (b):
The above expression can assume only value for b, and the value is:
This means that only will make the equation true.
<em>The reason for this is because the expression is an equation</em>
