a.
b.
a.

Whether
Answer to Problem 1PCT
Yes,
Explanation of Solution
Definition used:
Solution of a linear equation:
The value(s) of the variable that satisfies the equation or makes the equation a true statement is known as solution(s) of a linear equation.
Calculation:
Consider the linear equation
Replace the variable x with
Simplify the values.
Simplify further as follows.
Here, both sides of the equation are equal when the variable x is replaced by
Therefore,
b.
