Concept explainers
To solve the equation:
Also determine whether the equation is an identity or has no solution.
Answer to Problem 21WE
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 has no solution.
- Steps to solve a linear equation:
- Use distributive property to eliminate any grouping symbol.
- Simplify the expression in each side of the equation.
- Collect the variables on one side of the equation and the constants on the other side.
- Isolate the variable
Calculation:
In order to solve the equation:
First, collect the variables on one side of the equation and the constants on the other side, as
First, isolate the variable by dividing both sides of above by 10, as
Thus, the given equation has one solution
