Math Problem Statement

6[2 − (2x − 2)] = 2(6 − 3x)

Solution

Let's solve the equation step by step:

6[2(2x2)]=2(63x)6[2 - (2x - 2)] = 2(6 - 3x)

Step 1: Simplify inside the brackets

First, simplify inside the square brackets on the left-hand side:

2(2x2)=22x+2=42x2 - (2x - 2) = 2 - 2x + 2 = 4 - 2x

So, the equation becomes:

6(42x)=2(63x)6(4 - 2x) = 2(6 - 3x)

Step 2: Distribute the 6 and the 2

Distribute the numbers outside the parentheses:

6×(42x)=2412x6 \times (4 - 2x) = 24 - 12x 2×(63x)=126x2 \times (6 - 3x) = 12 - 6x

Now, the equation is:

2412x=126x24 - 12x = 12 - 6x

Step 3: Collect like terms

Move all the xx-terms to one side and the constant terms to the other side. Subtract 12 from both sides:

2412x12=126x1224 - 12x - 12 = 12 - 6x - 12 1212x=6x12 - 12x = -6x

Now, add 12x12x to both sides:

12=6x12 = 6x

Step 4: Solve for xx

Divide both sides by 6:

x=2x = 2

Final Answer:

The solution is x=2x = 2.
