Math Problem Statement

3x+8=x-4(x-2)

Solution

Let's solve the equation step-by-step:

We start with:

3x+8=x4(x2)3x + 8 = x - 4(x - 2)

Step 1: Expand the expression on the right-hand side

Distribute 4-4 to both terms inside the parentheses:

3x+8=x4x+83x + 8 = x - 4x + 8

Step 2: Combine like terms on the right-hand side

Simplify the terms involving xx:

3x+8=3x+83x + 8 = -3x + 8

Step 3: Move all terms involving xx to one side

Add 3x3x to both sides to get all the xx-terms on one side:

3x+3x+8=83x + 3x + 8 = 8

Simplify:

6x+8=86x + 8 = 8

Step 4: Move constant terms to the other side

Subtract 88 from both sides:

6x=06x = 0

Step 5: Solve for xx

Divide both sides by 6:

x=0x = 0

Final Answer:

x=0x = 0
