Math Problem Statement

4(2x-5 ) =8x -5

Solution

To solve the equation 4(2x5)=8x54(2x - 5) = 8x - 5, let's go step by step:

Step 1: Expand the left-hand side

Distribute the 44 across (2x5)(2x - 5): 4(2x5)=42x45=8x204(2x - 5) = 4 \cdot 2x - 4 \cdot 5 = 8x - 20 So the equation becomes: 8x20=8x58x - 20 = 8x - 5

Step 2: Simplify the equation

Now, subtract 8x8x from both sides: 8x208x=8x58x8x - 20 - 8x = 8x - 5 - 8x This simplifies to: 20=5-20 = -5

Step 3: Interpret the result

Since 205-20 \neq -5, this is a contradiction. Therefore, the original equation has no solution.

Final Conclusion:

The equation is inconsistent, meaning there is no value of xx that satisfies the equation.
