Question

Solve the equation:
3x - x + 4 = 4(2x +1)

Answer 1

x = 0

Explanation:

3x - x + 4 = 4(2x +1)

2x + 4 = 8x + 4

2x - 8x = 4 - 4

-6x = 0

x = 0

Answer 2

x = 0

Explanation:

Step 1: Write equation

3x - x + 4 = 4(2x + 1)

Step 2: Solve for x

1. Distribute: 3x - x + 4 = 8x + 4
2. Combine like terms: 2x + 4 = 8x + 4
3. Subtract 2x on both sides: 4 = 6x + 4
4. Subtract 4 on both sides: 0 = 6x
5. Divide both sides by 6: x = 0

Step 3: Check

Plug in x to verify it's a solution.

3(0) - 0 + 4 = 4(2(0) + 1)

4 = 4(1)

4 = 4
