Justify your steps using the properties of equality and determine the number of solutions to the equation 3/2(4-8x)+5x=1-7x

1 answer

To solve the equation \( \frac{3}{2}(4 - 8x) + 5x = 1 - 7x \), we will follow a systematic approach and justify each step using properties of equality.

Step 1: Distribute \( \frac{3}{2} \) into \( (4 - 8x) \).

Using the Distributive Property:

\[ \frac{3}{2} \cdot 4 - \frac{3}{2} \cdot 8x = 6 - 12x \]

So, we can rewrite the equation as:

\[ 6 - 12x + 5x = 1 - 7x \]

Step 2: Combine like terms on the left side.

Combine the \( x \) terms:

\[ 6 - 12x + 5x = 6 - 7x \]

Now the equation is:

\[ 6 - 7x = 1 - 7x \]

Step 3: Add \( 7x \) to both sides to isolate the constants.

Adding \( 7x \) to both sides:

\[ 6 - 7x + 7x = 1 - 7x + 7x \]

This simplifies to:

\[ 6 = 1 \]

Step 4: Analyze the resulting equation.

The equation \( 6 = 1 \) is a contradiction, meaning that there are no values of \( x \) that can satisfy the original equation.

Conclusion

Since we derived a contradiction, the number of solutions to the equation \( \frac{3}{2}(4 - 8x) + 5x = 1 - 7x \) is:

\[ \boxed{0} \]
