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 apply the properties of equality step by step:

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

\[ \frac{3}{2} \cdot 4 - \frac{3}{2} \cdot 8x = \frac{12}{2} - \frac{24}{2}x = 6 - 12x \]

So, the equation becomes:

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

Step 2: Combine like terms on the left side

Combine \(-12x\) and \(5x\):

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

Step 3: Add \(7x\) to both sides

This helps to eliminate \(-7x\) from both sides:

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

This simplifies to:

\[ 6 = 1 \]

Step 4: Analyze the resulting equation

Since we have the statement \(6 = 1\), which is a contradiction (this statement is false), this indicates that there are no possible values of \(x\) that can satisfy the original equation.

Conclusion:

Thus, the number of solutions to the equation \(\frac{3}{2}(4 - 8x) + 5x = 1 - 7x\) is \(\boxed{0}\).
