Understanding the Equation: Breaking Down the Components

Before delving into the solution, let's dissect the equation to understand its constituent parts:

• 17x: This term represents a variable, 'x', multiplied by a constant, 17. The variable 'x' represents an unknown value we aim to determine.

• 17x/8: This term signifies the variable 'x', multiplied by 17, and then divided by 8. It's a fraction where the numerator is 17x and the denominator is 8. This term introduces a fractional coefficient, adding complexity to the equation.

• -10: This is a constant term, a fixed numerical value. It's a subtrahend, meaning it's subtracted from the other terms.

The equation combines these elements, linking them through subtraction operations. Understanding the individual parts is crucial for effectively tackling the entire equation.

Method 1: Solving through Simplification

The most straightforward approach to solving this equation involves simplifying it before isolating the variable 'x'. This method leverages the principles of combining like terms and applying inverse operations.

Step 1: Finding a Common Denominator

To combine the 'x' terms, we need a common denominator for the fractions. The current terms are 17x and 17x/8. The simplest common denominator is 8. We can rewrite 17x as (17x * 8)/8 = 136x/8.

Step 2: Combining Like Terms

Now we can rewrite the equation with the common denominator:

136x/8 - 17x/8 - 10 = 0

Combining the 'x' terms gives:

(136x - 17x)/8 - 10 = 0

This simplifies to:

119x/8 - 10 = 0

Step 3: Isolating the Variable

To isolate 'x', we first add 10 to both sides of the equation:

119x/8 = 10

Next, we multiply both sides by 8:

119x = 80

Finally, we divide both sides by 119:

x = 80/119

Therefore, the solution to the equation using this method is x = 80/119. This is an exact solution, expressed as an irreducible fraction.

Method 2: Solving using the Distributive Property

An alternative approach uses the distributive property to simplify the equation before solving for 'x'. While less efficient in this specific instance, understanding this method is valuable for tackling more complex equations.

Step 1: Factoring Out 17x

Notice that both terms containing 'x' share a common factor, 17x. We can factor this out using the distributive property:

17x(1 - 1/8) - 10 = 0

Step 2: Simplifying the Parentheses

The expression within the parentheses simplifies to:

17x(7/8) - 10 = 0

Step 3: Isolating the Variable

Following the same steps as in Method 1, we add 10 to both sides:

17x(7/8) = 10

Then, we multiply both sides by 8/7:

17x = 80/7

Finally, we divide both sides by 17:

x = (80/7) / 17 = 80/119

Again, the solution is x = 80/119. This demonstrates that different approaches can lead to the same correct solution.

Verifying the Solution

It's crucial to verify the solution by substituting it back into the original equation:

17(80/119) - 17(80/119)/8 - 10

Simplifying this expression will confirm whether the solution is correct. This step is essential for identifying potential errors in the calculation process. Performing the calculation will show that the left-hand side indeed equals zero, validating our solution.
