To solve the equation:
Also determine whether the equation is an identity or has no solution.
Answer to Problem 30WE
Equation has only one solution
Explanation of Solution
Given:
Concept Used:
- An equation that is true for all the values of variable has infinitely many solutions. And an equation that is not true for any value of the variable has no solution.
- Steps to solve a linear equation:
- Use distributive property to remove any grouping symbol.
- Simplify the expression in each side of the equation.
- Collect the variable terms on one side of the equation and the constant on the other side.
- Isolate the variable
Calculation:
In order to solve the equation:
First, collect the variable terms on one side of the equation and the constant on the other side.
For that start by multiplying both sides of given equation with 7 and then simplify further, as
Now, isolate the variable by dividing both sides of above equation by 46, as
Thus, the given equation has one solution
