To solve: the equation
Also determine whether the equation is an identity or has no solution.

Answer to Problem 25WE
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, isolate the variable first by multiplying both sides of above with 5, as
Now, collect the variables on one side of the equation and the constants on the other side, as
Thus, the given equation has one solution

- 6) A farmer has 60 acres on which to plant oats or corn. Each acre of oats requires 100 lbs of fertilizer and 1 hour of labor. Each acre of corn requires 50 lbs of fertilizer and 2 hours of labor. The farmer has 5000 lbs of fertilizer and 100 hours available for labor. If the profit is $60 from each acre of oats and $100 from each acre of corn, what planting combination will produce the greatest total profit? a) Fill in the following chart to help organize the information given in the problem: Oats Labor Fertilizer Land Profit b) Write down the question of interest.
