Math Problem Statement

-2(x - 4) - x = -(4x - 10)

Solution

The equation from the image is:

2(x4)x=(4x10)-2(x - 4) - x = -(4x - 10)

Let's solve this step by step.

Step 1: Distribute the terms.

Distribute the 2-2 on the left-hand side and the negative sign on the right-hand side:

2(x4)=2x+8-2(x - 4) = -2x + 8 (4x10)=4x+10-(4x - 10) = -4x + 10

So, the equation becomes:

2x+8x=4x+10-2x + 8 - x = -4x + 10

Step 2: Combine like terms.

On the left-hand side:

2xx=3x-2x - x = -3x

Thus, the equation is now:

3x+8=4x+10-3x + 8 = -4x + 10

Step 3: Move all xx-terms to one side.

Add 4x4x to both sides:

3x+4x+8=10-3x + 4x + 8 = 10 x+8=10x + 8 = 10

Step 4: Isolate xx.

Subtract 8 from both sides:

x=108x = 10 - 8 x=2x = 2

The solution is x=2x = 2.
