negative 4 left parenthesis 4 x minus 5 right parenthesis equals 4 x

1 answer

To solve the equation \(-4(4x - 5) = 4x\), let's begin by distributing \(-4\) on the left side:

\[ -4(4x - 5) = -4 \cdot 4x + (-4) \cdot (-5) = -16x + 20 \]

So, the equation becomes:

\[ -16x + 20 = 4x \]

Next, we can move all terms involving \(x\) to one side of the equation. To do this, add \(16x\) to both sides:

\[ 20 = 4x + 16x \]

This simplifies to:

\[ 20 = 20x \]

Now, divide both sides by 20:

\[ x = 1 \]

Thus, the solution to the equation is:

\[ \boxed{1} \]
