4(5*x*−7)=−4(−5*x*+7)

The equation has infinitely/no/one solution

Let's solve the equation step by step to determine whether it has infinitely many solutions, no solution, or exactly one solution.

The equation is:

\[
4(5x - 7) = -4(-5x + 7)
\]

### Step 1: Distribute both sides
On the left-hand side:

\[
4(5x - 7) = 4 \cdot 5x - 4 \cdot 7 = 20x - 28
\]

On the right-hand side:

\[
-4(-5x + 7) = -4 \cdot (-5x) - 4 \cdot 7 = 20x - 28
\]

So, the equation simplifies to:

\[
20x - 28 = 20x - 28
\]

### Step 2: Subtract \( 20x \) from both sides
\[
20x - 28 - 20x = 20x - 28 - 20x
\]
\[
-28 = -28
\]

### Conclusion:
This results in a true statement, \( -28 = -28 \), which holds for **any value of \(x\)**.

Thus, the equation has **infinitely many solutions**.
